A bug with freezing

I am currently using beta on Xbox 1 Minecraft. I have come across a problem where it freezes up the screen. It is incredibly annoying!!! I was once in a build competition Is this with Minecraft its self or the beta? I have reasons to believe it is not my console because I have to exit Minecraft to get it working again. Please get it fixed!!! It freezes everything and I have to reload. Fix this ASAP.
