[Current Issue] Sims 3 "serious error" when loading save

hello folks,

I had installed and played Sims 3 yesterday. Today I get serious probloms bla bla bla. I had clear the cache, I had stopped one drive, I had repaired the game, I had reinstalled it. Nothing helps at my windoof 11 system. Sims 4 runs without any problems, wth is going on here with my Sims 3 base game. I could not start either a new game, it is alway stopping with the world crash of Sunset Valley.
