PS4 Is my game file corrupted ps5

[Pattycakes]

So I was playing today on a co-op world when my internet disconnected.

when I turned the game on there was a safe file but the name has since changed and now my team mate on another ps4 can’t play.

it seems like the game has corrupted and gone offline. Is there anyway to fix this?

Day 3 still no fix, restarted all the systems including internet and still unable to join back to old world, I noticed the save files character has changed, save time 000 and the name of the farm has changed.

any help would be appreciated really not wanting to start a new world. When in game, most things look normal however the 2nd player from a different console can’t join.
