Have you added any mods to the World or maybe accidentally shut down the playstation incorrectly while on the world? Sounds like Corruption >.> ^TK

We have two things we can try here! First, can you just connect your Playstation 5 to a hardwire connection to see if it allows you into the World. Second, if not create a new World and see if it allows you to enter that World. Let me know the outcome! ^TK
