Crashes to dashboard 30 seconds after it starts

IM ON XBOX ONE. AND MY MINECRAFT BETTER TOGETHER WAS WORKING JUST FINE FOR A DAY AND A HALF . BUT NOW WHEN I LAUNCH THE GAME IT GOES TO THE FIRST SCREEN THAT SAYS MOJANG IN BIG LETTERS. IT SITS THERE FOR ABOUT 30 SECONDS THEN CRASHES BACK TO THE DASHBOARD. I GET A MESSAGE SAYING PLEASE TRY AGAIN AND ERROR CODE 0x80040200. IVE TRIED REBOOTING,HARD RESET, PULLING THE POWER CABLE, DELETING MY SAVES, REINSTALLING 4 TIMES NOW, MOVING IT TO A DIFFERENT HARD DRIVE, TRYING A DIFFERENT ACCOUNT. NOTHING WORKS. XBOX SUPPORT TOLD ME TO COME HERE THEY DIDNT KNOW WHAT TO DO EITHER.
