Better together Update crashes on my Xbox One

When I open the Minecraft game on my Xbox one it Crashes
And it always says this "If this keeps on happening hold the power button for ten seconds then after that try again"
I did what they said and it didn't work

I uninstalled the game and installed it back and it still crashes

I have deleted all of my data and still crashes

Now I can't even play the game any more

But if you read this report, please fix this problem because it's happening to my friends and other people. Maybe in the 1.2.1 update?
