Failed sync user data

Hello. Everytime I try to get on my main world it says it failed to sync user data. However if I go to any other world it lets me on. It started this when I adjusted my settings to make my x box my home x box. However this cut off the game share I had with my brother and I lost the ability to play Minecraft. When I reset my world no longer let me get on. I have tried deleting and reinstalling. This occured on my x box one, however I am now playing on x box series s and still have the gameshare up. Any answers would greatly be appreciated. I'm trying to make it a realm.

:)
