Over the past couple of days I have been getting this warning when I try to run my SteamVR project (this never happened before). Unity just won’t recognize that steam VR is running. I have no clue how to fix it because every time it goes away it’s after I stop and start the game a could of times but this does not always fix the problem. SteamVR itself works just fine I can play games and even open the build of the same project. It’s just a problem in the editor. This absolutely kills my productivity because it can go for hours in end (I have also had times where it went away in 5 minutes but like I said, I have no clue why).
Fixed it. at least for now. I unchecked and checked the Initialize XR on Startup In the XR plug-in management
