Can't access saves in menu (Sims Medieval)

I'm on PC, using the latest BS Windows (Windows 11, version 24H2) has put out and now Sims Medieval is not accessing my saves. 

I can open the game, start a new game, play the game and even save the game but once I leave and come back the save is nowhere to be found on the menu. I know I have the save. I see it in my files! The game even tells me I can't name my save the same thing as a file that already exists. 

I've had a save on there before it worked and was fine but that before the update in 2024. I haven't played in a really long time so I'm thinking it's the Windows 11, version 24H2 that's the problem. I just want to know if I need to downgrade to windows 10 again. Unfortunately, I don't know if or what version Medieval worked with Windows 11. I also can't remember this being a problem before but it always was I just got lucky before.

What I've tired that did not work:

• looking for answers here but can't find my specific problem. 
• uninstalling and reinstalling the game
• moving my saves around 
• starting new saves (no save file is ever found on the menu)
• cleared caches
• repair in EA launcher
• tried renaming the file (worked but then the same issue occurred after trying to save it again)

I'm not sure what else to do other then getting windows 10 back on my PC but I'd rather not do that if there's another fix.
