[MCPE-20548] When I want to sign in Xbox I click the button and it crashes my whole game

So I have tried deleting the game and reinstalling but nothing works even shutting of my phone so it resets. All I do is get on minecraft click the sign in button for Xbox live and then it crashes

Possible workarounds

A couple of workarounds have been suggested in the comments:

Ramona Hopkins comments here that turning off WiFi might solve the problem, and gives helpful information on how to turn it off.

Andrew Kasper comments here about how deleting a certain file might solve the problem, if you have that file.

We would appreciate you letting us know if you tried either of these workarounds and whether or not it helped you.
