Failed to Sync World Beta.

The error is, "failed to sync the world, The world is not fully synced or has been corrupted."

I logged in today and the game crashed as the world was loading. After restarting the game the world was lost. 

I then had to delete my xbox account hard reset my xbox and relog into my xbox account TO EVEN SEE THE WORLD ON THE SERVER LIST.

Then when I click on the world I get this error. I have uninstalled and reinstalled countless times. Whats the fix.
