I got the same thing, and the "prefab" answer about using "HELP" "get my self" unstuck won't work, IF YOU CAN'T even get the character to load into the game.
Took me a week w/ support to get them to understand and move my character for me....
Ok guys! Listen to me now! I solved my problem. I updated my ps4 logged in there changed the zone of my character via ps4 and now I can access my character on ps5.
I don’t know what to do if you don’t have both consoles but if you have both, that’s the solution
