System Crash when playing Minecraft

There will be times when im playing Minecraft, that my Xbox will stop functioning properly and then Hard Crash soon after. This issue happens Every Single time i try to play, the only thing that differs is how long i can play before it happens.
Also, sometimes when this occurs it will Delete the world i was playing in.

Example Below
My Xbox Guide will stop appearing and just create a darkened screen and i cannot do anything with my Xbox such as Menus, Profiles, Messages etc without it just Darkening my Screen and then Hard Crashing my Console. This only happens when i play the New Minecraft Better Together
