Rendering problem in VR mode (black screens after launching the game)

Cannot use VR mode on the WMR (Windows mixed reality) headset
model HP VR1000.

1- I checked in the task manager, I have the game and runtime broker.exe linked but they don't have a gpu assigned

2- I forced the startup on the two gpu that my computer have and no change, I also launched the game via the OpenXR shortcut.

3- I forced Windows portal to use the developer mode and launch the game in VR mode with the simulation of a headset, the game is displayed, but the camera does freakout.

4- in the manager the game and runtime broker.exe have the gpu assigned correctly in simulation.

verdict: it seems that there is a problem between the headset and the game, a driver conflict?

What I was expecting was... :
that the game would work fine or indicate an error but no nothing at all

What actually happened was... :
the launching of the game is done correctly but does not seem to succeed in loading the graphic rendering.

Steps to replicate:
1 connect a windows mixed reality headset
2 launch minecraft with or without the openXR shortcut and wait
