Xbox btu crashes everytime

I was playing in INPVP with some friends, I was in the hub and I opened chat to type something. It let me type at first and then froze after a few letters. Then my game crashed. Now whenever I try to load the game, it crashes after the mojang logo. This happened when it was still beta. It lasted for 4-5 days. I thought it was fixed in the final version cause it was working correctly for a few days. But its not. I hope this was helpful
