Possible corruption

Hello, I will try to explain my situation as best as I can. I own all expansion packs, all game packs and all stuff packs, and I do use mods. I last played the game on April 2nd, I experienced no issues, no lag and no weird bugs. Cut to April 4th where I try to play the game again- the game will not open at all and would immediately crash on startup. Initially I thought it was Steam or the EA app being odd, so I uninstalled the EA app and nothing changed. I uninstalled the Sims itself and nothing changed. I took out every single mod and tried to run the game, but it still wouldn't open even without mods. Fearing the worst, I removed all of my save files and ran the game again, unfortunately it opened. I put my save files back in and the game went right back to crashing on startup. The game will open without my save files + mods perfectly fine, so does that indicate my save files are corrupted? If so, is there anyway to possibly recover them or fix them?
