If a player dies in a world on Hardcore mode, and chooses the "Delete World" prompt, multiple errors occur. The game goes to the main menu. The "death screen" without the UI is used as a background for options, and realms. The main menu has a light gray background instead of the typical panorama. The game also continues to play sound effects from the world that was just lost while the menu main menu is navigated. Then, if the player goes to the world select and attempts to play the world they just died in from the world select, the game goes to a black screen and is unresponsive. Then, when the game is relaunched, and the player selects the world again (which was not deleted), and chooses to play it, they will be taken to their death screen, and they have the typical options of spectating or deleting the world. If they choose to spectate, the game functions normally.

The following videos have a few rendering issues (with the recording software, not game) when the world is first generated, but it still showcases the bug completely. I would send the video file by itself rather than a youtube video, but the file is too large to attach. In case the youtube videos are not sufficient, I have screenshots attached.

I hope this is enough for the issue to be found, thank you for reading
