@HonoraryAngel59 Pull your Sims 4 game folder out of Documents\Electronic Arts and try to launch the game. Does it work? If so, a clean game folder will be created in Documents\EA. You can transfer the contents of the Saves and Tray folders (and Mods if you use them) from your old game folder to your new one and continue playing.
