There was a world in my world list that had been created before I owned the game. It asked me to 'attempt to restore' before telling me that it could not be restored and to report the issue here. (The world was created on 14/9/24, I purchased the game on 13/1/25) The world name was '2EfeZufZBQA='. I did not create it.

What I expected to happen was...:

The world was not meant to be there in the first place. I expected it to just restore.

What actually happened was...:

The world did not restore, I have no idea why it is even there.

Steps to Reproduce:
1. Enter Minecraft: Java Edition.
2. Click 'singleplayer'.
3. The world was in my worlds list, however I am unsure if the bug will be able to be reproduced.
