Might be happening when the "Windows Mixed Reality" Virtual Reality SDK is missing in the XR Settings of the Player Settings.

I have this settings

Seems similar to this report:

https://github.com/microsoft/MixedRealityToolkit-Unity/issues/5447

Note that the MRTK doesn't have control over how Unity renders things on the device (if it could, that would be interesting... but weird... but interesting!).

For simplicity's sake, I would just try to get things working WITHOUT the MRTK, and you should be able to then copy the exact settings and get things to work with the MRTK.

I remember hearing about a buggy WMR package (i.e. UPM package) - I used 1.0.12 recently which works fine.

It was actually in the XR settings with the "WSA Holographic...".
Problem solved, thank you.
