I can’t access any of my old worlds?

I play on xbox one s with and without gamepass, and the only world I’ve mainly played on is one I made in 2020, so I went to play today and it says I can’t play ANY of my previously made worlds because they’re multiplayer worlds?! I haven’t even played with anyone since I made the world in the first place. Idk what’s wrong, but it’d be pretty crazy to start to lock players old worlds behind a paywall when not having gamepass has never been a issue before.
