(Bug Request moved) rendering problem in VR mode (black screens after launching the game)

Moved to bedrock version.. 

when using the VR Windows Mixed Reality headset (old model) the game is launched with sound but the screen remains black on the return but also on the VR headset while if the developer mode is activated and I simulate my headset, the game menu is displayed but does anything.

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 game starts and a white ball animation indicates the loading but then nothing except the music of the game

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