Unexpected crashes

details -  Xbox One X - SSD drive - 740mb world

 

Recently I've started getting alot of crashes. Blocks will stop making sounds as they break or are placed.   Then the game fully closes and I'm back on the Xbox home screen.  Sometimes I get 10 minutes, sometimes it's an hour or so before the next crash.

 

I tried out one of the  Nether update betas recently, but that has been removed.
