Cannot start a mission with MT client. ST client will no longer use OpenXR for VR.

I can only play the game with the ST client. The MT client has crashed on mission load for the last 3 releases. I was getting decent performance with the ST client in VR and using OpenXR so it wasn't much of an issue for me until 2.9.  Now with 2.9 with VR it always launches the MT client, which will load to the menu.  Once I try to do an instant action, join a multiplayer server, or anything where I am actually flying it crashes to desktop.

Game is installed on an SSD (all I have) in 2.8 ST worked fine with OpenXR and VR, now I can get VR working but only with SteamVR, OpenXR does not activate.

I have used DDU to completely uninstall my video driver and re-installed (which actually fixed my in game overlay that wasn't working in GeForce Experience, but still have the same issues in DCS.

Would like to use MT but it crashes and I haven't been able to find a cause. I have repaired using slow and removing extra files multiple times, I have removed my Saved games folder and let it regenerate, still have the same issue.

Finally figured this out. Turns out it was a XRNeckSafer json file that was linked in the registry at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ApiLayers\Implicit

I now have MT running in VR again just have to break my neck to look behind me
