Xbox live bug that makes MCPE unplayable

I was playing Minecraft while I was away, without wifi, the game signed me out of my Xbox live account, like it should. I came back home with wifi, and things were still normal. Until I signed into my Xbox live account again. After signing in, I pressed play and the game was frozen. I went out of Minecraft and swiped up the application and went back in, and I couldn’t get past the loading screen without the game freezing up! No troubleshooting would fix the problem! The game could not be played!
