Window Mixed Reality VR not tracking

[LB31]

Hi people,
I wanted to give the Action-based XR Rig a try in my project. In Play mode I only have a frozen picture.
Then I downloaded this project and have the same problem in the WorlInteractionDemo scene. DeprecatedWorldInteractionDemo on the other hand works fine with the WMR.

I even tried adding bindings especially for the WMR in the Main Camera of the XR Rig and in the Input Actions window.
This was also unsuccessful.

Do you have an idea how I can fix this problem?

Same problem here. WMR doesnt work with the XR Rig. Only works with the deprecated example.

I am experiencing the same phenomenon.
