i have the same, i stopped playing with mods a while ago so i know its not that. after loading into the sims whenever it hits a point where it needs to do something, entering cas, loading a save, going from build mode to live mode, saving, etc my game screen will go completely black or white and i cant close the game without entering task manager. what's weirder is that for me the music keeps playing and i can technically still interact with the game, i just cant see what im interacting with. my mouse is still visible even once the screen has gone black/white too. my game is fully updated, im playing on the lowest settings possible because my laptop is about 7 years old. other games run fine like the sims 2 legacy edition, the sims medieval, the sims 3, etc along with other games on steam not EA.
