When I start DeoVr up, it'll be a little choppy before completely freezing. Headset tracking will still work, but DeoVr isn't drawing anything new. When I take my headset off, my graphics driver has notified me of a crash. I don't see graphic driver crashes normally and can run other VR apps fine, so something is going wrong with DeoVr's interaction with my graphics driver.
This is my setup:
Radeon 6900xt GPU (AMD Driver version 22.7.1 from 7/25/2022, no new updates)
Valve Index Headset with 4 base stations
Let me know if you need more system info or anything else to help diagnose. Sometimes I can maybe get a single video to play before the graphics driver crash, but it usually happens within 10-15 seconds of DeoVR opening, before I even play a video.
