Issues with possible VRAM memory leak in VR

[StanS]

I have started experiencing a strange issue on Sunday in VR, which is so far only exclusive to IL-2. Whenever I start up the game, my VRAM usage shoots up from approximately 5GB to 10GB and stays there while only staying in my menu screen. Then, after I start flying (irrespective of whether this is in single player or multi player), the game crashes soon after, no more than 30 minutes after the start. The resulting NET framework error is indicating a lack of available memory.

What is even more interesting is that if I decide to exit IL-2, even without doing any flying, fpsVR will report that approximately 9GB of VRAM are still being used, even though nothing else is running (not even SteamVR Home). This only happens after I launch IL-2, with other games I have around 5GB being used with nothing else running. I tried downgrading my GPU drivers, and I tried reinstalling IL-2 to no avail.

I am using a Reverb G2, with an I9-9900K (OC to 5.0GHz), and an RTX2080TI. 

Has anyone else experienced a similar issue? Any help will be much appreciated.
