Hey, I'm sorry about that. Have you also tried to uninstall and reinstall the game and as well try rebulding the database on your PS4 to see if that helps?
If you are still experiencing the same issue the best suggestion would be to reach out to official support and Playstation Support for further assistance. They will be able to gather more information and assist further as soon as possible. You can reach out to official support here:
