I'm sure theres more than enough data to troubleshoot, but I'm having the same issue, After loading in the game runs perfectly for about 2 minutes and then hangs for about 15-20 seconds and then just exits, no error code or anything just straight to desktop. Tried fresh drivers, all windows updates, deleting shaders and disabling them as well. Admin and disable fullscreen optimizations. very strange. 9900k 3080
