Worlds disappear after save and quit while offline

Issue: My forever world I started in July of 2023 is missing while playing offline after save and quit.

What happened: I am currently offline playing due to internet being off currently, wanted to worrk on my long time world and spent 6 hours on my project, and saved and quit. When I woke up today my world is completely gone, it's in the storage section of the of settings however (this need a play button for these).

Is this repeatable: Yes, I checked one of my back up worlds, loaded it flew around, save and quit, and that world is now gone also.

I made an attempt to get the world sync wit phones hotspot, but it is not syncing worlds either.

Offline mode needs to be fixed, please.

There should be no reason my world vanished while offline, and playing offline is what I have done for years without internet, and now the first time in 10 years I don't have internet the world I have spent the longest amount of time on is completely gone, and I'm heartbroken about it, because I used to play offline and never lost a world before.

Please, look into this and see if the world can be recovered.

I've attached screenshots from in game of the storage in settings, and the worlds.
