hello, i have the same problem and when i relocate the whole folder, the sims is working, but my previous households get deleted so i have to start playing with creating a new family over and over. its a two-tailed situation - either i can play sims 3 but only with starting a new family to which i later cant get to or the family (which i created earlier) is there but the serious error about restarting the application pops up so i cant play with that family. hope its understandable, english is not my motherlanguage🙂
I have this same issue but i already uninstalled OneDrive. i don't know whats going on with my game
