Update: I actually found a solution/fix.
First: I was just silly and missed 1 street art I didn't know about so that was solved quickly.
(But for the glitched trophy):
- I found a USB to copy my game progression save data onto (as well as the wrap and profile data too just in case).
- Deleted the save game progression data from the PS4
- Restarted the game from the start, and reclaimed the trophy.
- From there, I exited the game, deleted the save data again, and reinstalled all my save data back onto my PS4 from my USB, including the wrap and profile data just to make sure it didn't remove or update with the new save.
Hopefully I don't run into another trophy problem. But now I can finish my trophy run for the platinum.
