Me and my friend have been playing a Minecraft world for almost a month, but the last week this error appeared "Error while syncing world data (The world is not totally in sync or is corrupted. Try to play in this world with a console that is in good condition and then try again to migrate the file.)"

I have already deleted Minecraft, deleted my account, make another account, restart the Xbox, enter Minecraft on another device (iPad) and nothing has worked.

After all this, I don't know what else to do and i don't really want to lose the world.
