I was bouncing back and forth between SteamVR and WMR headsets while testing functionality and managed to hard lock the entire system (Ctrl+Alt+Del wouldn’t even respond).
This occurred as I had powered off the Vive and powered on the G2 (WMR) without first closing SteamVR.
When the computer finally came back, I was greeted with the below warning, and a total editor shutdown.
Not yet as I haven’t tried to replicate the lockup yet. Certainly something I’ll have to spin up a clean project to do so as I don’t wanna risk corruption of data.
