Game Startup...Crash

[J37_Spyboy]

I was being returned to the opening screen when I tried to join a server, so I have cleared the Updater folders from IL2. The launcher screen verified the files and when I press play I get a little box . I haven't used VR for 6 or 7 months, am unable to at present. Can someone tell me what this is and how to solve it.  Meta Quest software have a driver update but I don't think that will solve the problem. I would put this on IL2 Forum, but from tomorrow no one will be able to write any reply! I have placed it here anyway.
