I'm sorry to hear that, might i ask your specs like windows version, graphics card etc? I heard about that crash but unfortunatly can't recreate it on my machine
i also have it and i have a rtx1650 super i5 and 16 gb of ram and steam vr open with it for some reason and it even happen in the home screen and it even happen after deleting steam vr
i maybe know why it keep crashing by unreal engine 5 plugin for steam vr is enable and if it cant find it game will over load on finding vr and if it cant find it or steam is not close or stuff like that it crashes i found a video on youtube saying that link to the video
and i see steam vr open up every time i start the game and even deleting it wont work and by my other pc it open the quest laucher so something is going wrong
