If you have this address, then you should be able to launch VR with the Ctrl + Tab shortcut. Unless OpenXR is not activated …
I tried looking for a solution, but other than reinstalling Windows 10 I couldn’t find anything.
If you are lucky enough to have System Restore enabled, you can try to restore before installing any VR apps.
Personally, I have 2 Windows 10 installations on my PC. With one I have no problem, apart from these crashes in VR with the RX 6800 XT and the HB Reverb G2.
On the 2nd installation, which is a clone of the first, I have no sound coming out of the HB Reverb G2.
This is what have been called: The joys of computing.
You can try with the SteamVR runtime (Installs steamVR)
In the registry you change this address C: WINDOWS system32 MixedRealityRuntime.json
By that one
C: \ Program Files (x86) Steam \ steamapps \ SteamVR \ steamvr_win64.json
Check it out, so you never know (I haven’t read it)
Don’t set location of OpenXR runtime with the registry, use OpenXR Lo
