Having exact same issue on PS5. So far the only way I can still access my world is by uploading saved world data to PSN cloud and deleting said world from local storage and then downloading it back to local storage on the system which is just great experience overall 10/10 would totally recommend... Also this doesn't always work so I keep trying it until it works, sometimes I delete all saved data of Minecraft that is in local storage...
