Earlier today I was casually playing and exploring the end where I unexpectedly crashed for no reason. Upon reloading I noticed my mini-map and map were corrupted in a way where many of the blocks were air and completely black as seen in this image.

Also stemming from the crash was the wiping of all in game advancements but not quests. In either scenario I have tried reloading many times in many different ways but cannot seem to fix the problem. Any solution/fix?
