show stopper bug on windows 10 mixed realty in vr minecraft

I selected geer vr as you do not have a windows 10 mixed reality vr option. I talked about this bug in a previous post. it was never fixed. 

https://bugs.mojang.com/browse/MCPE-34562

 

Here is a live stream I was doing. where you can see the moment I die and cant respawn. https://www.youtube.com/watch?v=maATg6pM-0M&feature=youtu.be&t=1439

 

what happens is im playing minecraft vr after about 10 min or so I cant open any menues and I cant respawn when I die. a side issue with menues is there is no way to close minecraft in vr.

 

when I click the windows key it goes back to the sky house view but minecraft is still open in the background. I can only close it with task manager.

 

so far this is the only way I can get past this menue issue when it happens. force close minecraft. please fix this.
