Replay missions not loading

I’m in the middle of a platinum run and am working on getting 70 gold medals now that I’ve gotten 100%, but am getting stuck on infinite loading screens when trying to replay missions. I tried clearing my cache, starting a new game then going back to my manual save, and now deleting and reinstalling the game. If that doesn’t work I have now clue what else I can try. It would be extremely disappointing to give up on the platinum after spending hundreds of hours of grinding that 100% and online trophies.
