Game keeps freezing

My game keeps freezing around 4 AM on sundays and I have to use task manager to exit the game. I've tried removing mods, repairing the game, creating a new EA folder, creating a new save file but nothing seems to work. I've managed to play for a sim week on my new save file before it happened again. I really don't know what to do anymore. I don't know which files to attach to help me find the problem.
