Finding the cause of a random crash issue (Special Thread #1)

[-DED-Rapidus]

@BobG, please read the first message.

[plepew]

@-DED-Rapidus I'm using Windows 10, but with the latest update (4.704) the problem seems to have resolved!  I was getting it every time I exited the game following 4.703 and haven't seen it once since the .704 update.

[nniless]

Hi, i'm on the latest steam version of the game. On AQMB I am getting perfectly normal performance until  (somewhat - might be playtime per mission) the game freezes, although UI elements (turning hud on/off, tab window, command window) are responsive. Attempting to exit the game through the pause menu makes then game completely unresponsive before crashing. I have zero issues prior to today. I should note I have tried only on the bodenplatte map, with spitfire (that comes with BOBP) and the tempest.

 

Specs:

AMD Ryzen 5 5600H

8 GB RAM
NVIDIA GeForce RTX 3050 GPU 4GB 

(latest drivers installed)

 

I have a crash dump which i have attached. i am getting the exception 0x0000087A

 

Update: I tried reinstalling on steam. after loading up a AQM and trying to start the mission, the game crashes with the error message:

"The instruction 0x00000268E5663A1A referenced memory at 0x0000000000000000. The memory could not be read.

Click on OK to terminate the error"

@nniless, Unfortunately, I can't reproduce the problem. If you CTD repeat ,  save the _gen.mission mission file. The file is located in the \il2\data\missions folder.

@Quax, I need a video with the playback of the problem, can you record a video of how CTD happens?

[Quax]

SOLVED:  SteamVR was running in the background. Switching it off didn´t help. 

                 After deinstalling and rebooting it is good again. Sorry for taking your time ?

- Game crashes immediately on startup.  Screen goes to black per normal, but before the title splash appears it dumps me back on my desktop.  No error messages.

- No game mode; can't even start the game!!

-Downloaded latest update through Steam, then tried to run game

-Again, can't even get into the game

-I have the Steam version of BOS, but all other expansions, aircraft, etc have been purchased directly through 1C store.  I did try the "verify installation" option through Steam and it found several corrupted files (around 150+) and redownloaded the corresponding files.  It made no change whatsoever.

If you have a preset of low graphics settings, then you need to change it to balanced. A hotfix will be released soon, we apologize for the problems caused.

Hi DED,

 

i have everything maxed out, no low graphic settings.

 

No problem, things like that happens.

I was always on the lucky side until now.

 

The most important thing is, you are aware on this problem and you all give the best to give us a hotfix.

 

Thank you

Can’t get into the game to set my graphics, but I recall they shouldn’t be set to minimums. 
Grateful for all the urgency and extra effort you guys are putting into setting things straight. Looking forward to that hotfix!

Update:

Just downloaded something through Steam (I assume it was the hotfix?  Was about 7mb).  No change; goes to black screen, title splash never appears, then right back to the desktop.  Tried verifying files again and restarting; made no difference.

Please disable the mod option at startup. It looks like you have textures in your graphics\texture folder that are causing the game to crash.

I can’t get *to* startup to disable them. Is there an option/method to turn them off in a .config file in the game directory?

[Yankee_One]

@-DED-Rapidus

 

Hi,

 

i disabled the "mods on" startup, its working.

Enabling them causes the crash.

 

I send you some crash dumps.

 

I found the folder wich causes the crash.

Its called "effects"

 

Its an mod called the 2nd WWII mod pack.

But there is a new version, the author recocnized the crashes and updated the mod.

 

After deleting this folder, i can enable mods again.

 

Thank you for your help. I really appreciate it. Thanks alot!!!!

This is probably my issue as well. I’ll see if I can just unload them or swap with the new version. 
 

Lesson learned: disable mods every time a new version comes out!!

Removed mods using JSGME and now I'm able to get in the game and everything appears to be working fine.  Thanks again for all the help!

The problem still remaind, at least for me.

 

I uninstall all mods every time before updating IL-2 or DCS. Thats a must!!!!!

 

The problem was, that this particular mod did not uninstall the folder with the files in it, even with JSGME.

 

You have to do it manually.

Hi,

Anyone playing on Linux/Steam/Proton? I have a startup issue since the 4.705 update. More detail here.

[=DFA=Sport]

Tried flying a Flying Circus stock mission "Alliez Kaput"  Crashed once upon loading in, then again a minute after taking off.  Using VR with OpenXR (not SteamVR)

 

i9 9900K

RTX 2080ti

32GB Ram

HP Reverb G2

 

Dumps:

 

Il-2.exe.13028.dmp.zip

[Nadelbaum]

Game starting crashing immediately during loading (after the loading bar seems to be fully completed). Black screen and dump back to Windows (this is Windows 11). Everything was working still this morning, but in the evening it doesn't load without a crash. I've turned MODS off, deleted startup.cfg, verified all files through Steam, nothing seems to work. I'm really puzzled. Dump attached.

 

Il-2.exe.2200.zip

[Gryphon_VR]

Hi, this ones in VR (HP Reverb G2v2 headset).

 

I've had a series of crashes over last week or so. In a Career or Quick mission, the game runs great for usually about 10-40 mins then I get a bright blue screen in headset, then black, audio reverts to desktop. I remove the headset to see IL2 is no longer running and I have an error popup from Open XR stating as follows:

C:\projects\openovr\DrvOpenXR\XrHMD.cpp:41 GetProjectionMatrix. Error code: -16 XrLocateViews(xr_session, &locateInfo, &state, XruEyeCount, &viewCount, views)

My hardware is intel 8600k, GTX 1070, 16GB RAM and I'm getting ~45 fps in IL2 with that. GPU memory use is just 6 of 8 GB.

I'm not using steam at all. I'm running IL2 -> Opencomposite -> OpenXR - Windows Mixed Reality -> Reverb G2. I have no mods in game, but I'm running the OpenXR Toolkit.

In my CrashDumps folder I have a set of .dmp files covering all my recent IL2 crashes of which the attached is the last (plus the opencomposite.log file). I cannot post the -gen.mission due to 5MB limit, but as this has happened in many different Career and Quick missions I don't think the mission is relevant.

[-DED-Rapidus]

@Gryphon962, @Nadelbaum, is there CTD? if yes, then we need fresh dumps after updating the game.

[Nadelbaum]

@-DED-Rapidus Yes, still CTD after update. But, I think I managed to narrow it down to campaignsstates.txt. It is also logical as the only thing I was doing between morning and evening was playing scripted campaigns and shutting down Il-2 for the day between.

 

I've attached a new dump and also the campaignsstates.txt. Here's what I see:

 

1) If the campaignsstates.txt is as-is -> CTD during startup

2) If I remove an entry for any one campaign completely from campaignsstates.txt file, but leave all the rest -> No CTD during startup! 

 

Leads me to make a conclusion that the size of the campaignsstates.txt is too big... I've basically downloaded every scripted campaign there is even if I haven't yet played all of them. (Note! I can basically remove any campaign from the campaignsstates.txt and all is well, this is why I concluded that it could be a file size issue).

Minor clarification added

[Gryphon_VR]

Yes, still getting crashes after update. However, based on other analysis I think that IL2 is not to blame, it seems to be a loss of connection from headset to PC which results in the OpenXR runtime and Opencomposite exiting, and that impacts IL2. 

 

Other than making the game a native OpenXR application (rather than SteamVR) I'm not sure what you could do. I hope the developers will look at that as the performance improvement of OpenXR over SteamVR is considerable, and that matters in VR.

[DarkHawk]

Hi,

 

I'm a new IL-2 user. I have the steam version of BOS and after 2 weeks of use, I couldn't launch the game anymore. I went to the extreme of removing it completely from my computer and reinstalling it from scratch. After reinstall, it is without any mod, no changes, but the CTD persists. Here's the dump file. If anyone can help me I would appreciate it. Currently I can't get to the initial game screen. It starts loading and after a while it crashes to desktop.

I am also having this issue, game loads, I join server everything is ok for about 15 minutes than game crashes and I can't restart game, pop up screen appears saying

System.Computer Model.Win32 Exception (0x80004005):Access is denied at System. Diagnostics Process.Start with shell execute Ex (Process Start Info start Info)

and it goes on on on.

all this started to happen after last update. So I have a spare version of game on standby that I use to get back in, and same thing happens over and over again with each spare game I use.

thanks in advance

[super-truite]

not sure if this is the right topic as it concerns DServer in my case:

* crash encountered after 10 or 15 minutes 
* scenario: PvP gamemode
*  what happened in the mission before the crash: after 10-15 minute what can occur is the spawn (with activate command) of 4 bombers,
so that might be when the crash occurs. The crash happens with low number of players as well (1-2). Server performance seems to be fine.
* I use a lot of remote console calls, but it was not causing any issue before

PS: anyway of reading those files ?  (WinDbg for those interested)

[-DED-Rapidus]

@super-truite, can I get the mission file from you?

[super-truite]

sure, here it is, after further tests, the crash seems to come from an AI tank group (called AI tanks).
The only difference compared to other missions where I use the same group is that the tanks have some individual Command formation : on road. 
The group is randomized so it is yet unclear which exact unit is causing troubles. Not 100% it comes from this group though but the server managed to hold till the end when I removed it. I will try to create a repro when I have the time.

Hey everyone, my game crashes after pressing PLAY on the launcher when trying to launch in VR. Works fine in normal non-VR mode. I tried reinstalling but didn't work.

EDIT: Update: works in SteamVR and not using OpenComposite, I guess the issue is a recent OpenComposite update that I made. Still, it doesn't work in OpenXR.

The crashes appeared:

• during the glight and at the end of a flight, just after clicking "finish mission";
• In campaign game mode 
• In missions of BlackSix campaign: last one of Steel birds campaign and mission 5 of His Majety's Griffons campaign;
• nothing in particular;

Had a crash tonight, the game put me back to desktop with the error (screenshot attached) then went black, had the mouse and the windows busy icon spin, then back to game which is shown in the screenshot.

 

System:

Gigabyte Aorus 1080Ti 11GB @ 3440x1440 Gsync

DDR4-3600 16GB

AMD R7 5800x

I was playing AQMB, D-Day Normandy map in morning - screenshots of AQMB settings included. 4 P51Bs, US skins, beachhead patrol. Enemy were 190A8s mix of clean fighter escort and ground attack loadout with bombs. P51s were setup with Mirrors, the -7 engine, 150octane plus 81manifold. Fight lasted 5 to 10 minutes, there were 3 of them left out of 12, 2 of my flight left of 4. I was cycling through external views of the enemy when the crash occurred. I noticed one of the enemy kept showing in the external view cycle even though it was submerged in the channel, and had been for a bit that I'd expect it should of despawned by then but not sure.

Been having CTD issues for months similar to those above me where there would be a black screen before it suddenly crashes. This time I think the cause of the issue was me fiddling around with the anti-aliasing settings (iirc it was switching from FXAA to MSAA, whether that was a good idea or not is up to your interpretation), I did a restart afterwards and ran into said problem, since then its done the same thing. My suspicion is that it had something to do with the 4.707 update as I was testing out the new (at the time) Me410.

In case it's useful, here's the graphic settings from the startup.cfg file.

[KEY = graphics]
    desktop_center = 1
    fps_limit = 60
    full_height = 1920
    full_width = 1080
    fullscreen = 0
    gamma = 1.00000
    mgpu_compatible = 0
    multisampling = 2
    preset = 2
    vsync = 0
    win_height = 720
    win_width = 1280
[END]

Any suggestions would be greatly apreciated.

Hello, I crashed 3 or four times during landing after completing a mission in the BoS campaign. I shot down a couple of plane and during final approach or shortly after touchdown I got a D3DX error (if I closed it it instantly popped back up again). What's weird is that, despite the image being frozen, I could hear planes moving and minding their own business as usual (so the game didn't freeze, task manager said it was responding, I was just locked out by this error)

 

The dumps are 6MB compressed, so I've uploaded 2 on Mediafire: https://www.mediafire.com/file/ernxt47qt5jiop7/Il-2.exe.13412.zip/file
