So. Many. Crashes!

Hey Mojang,
Ever since I created a XBox live account and have been logging in on it, Minecraft wont load and will crash. This also happens when I dont sign in too! I try to join a world, takes 5 minutes to load half, then it crashes. This is something that I think needs to be fixed. Its really annoying. So please, try to fix the issue.
