Sims 4 won't load past main menu

@Aristianassa  Please do a clean uninstall and reinstall of the Nvidia graphics driver, as described here:

But instead of using the newest driver, try one from December or January.  I've seen a couple of reports of Sims 4 not running well on the most recent drivers, not sufficient to say there's definitely a problem but enough to make it worth testing a slightly older driver.  You can update again whenever you want, and you can find a number of older drivers here:
