Thanks 199337790 and jackyshenjian, everything you stated worked perfectly. I was able to use your method to get this to work, thank you so much. For any other EU players, I've uploaded the plat save as per OP's thread, you can import this to the PS5 and it will insta pop all the trophies, loading this save on PS4 will only give you a few trophies.
