Make sure your headset is connected and running on the PC before you launch, and if you are using an Oculus Quest 2 or 3, I recommend using Meta's software and not steam Link, or Virtual Desktop, as those methods have not been tested. I also have only tested on a Quest 2 or 3 so if you are using something other than those headsets, it COULD be the issue. I know the game runs on Index and HTC Vive products from other users informing me. Let me know if any of this helps!
