*HELP!* Cannot use Minecraft signed into xbox

Heres how it started: Today I logged into Minecraft. But something was wrong. When it was loading, it crashed. It kept doing this. I tracked down the problem to.. Me being signed into Xbox.... What the?? The only way to get Minecraft to work was to reinstall it so it would sign me out of Xbox. If you signed back into xbox, it would freeze your game and when you tried to relog it would do the crashing thing again. Please fix this as soon as possible or else I will go insane. BTW my username is co8222. And thank you in advance.
