a random hole appeared in the middle of the game. once i jumped down it i sank and couldn't jump or move upward. once i hit the bottom it bugs out and i res cannot close the launcher.

one day while i was playing a random hole appeared in the middle of the game where a lake used to be. So naturally i jumped down it. once i jumped down it i just sank and couldn't jump or move upward. once i hit the bottom it bugs out and i re spawn at the top of the hole and the process repeats. The launcher reports a problem with my world and says server severe. please help! i also cannot close the launcher.
