All Households Disappeared

Hello, I'm currently having an issue with The Sims 4. I updated the game, and then when I started to play the first time, all my households were there, but when I went to create a new household, the sims don't show in CAS mode, so I couldn't see any of the sims or edit them. I did receive a "couldn't recognize my graphics card" warning and I just bypassed it, and I just created a random household to see if it works or not. It didn't. So I restarted the game hoping it would fix that, but when I restarted, all my households completely disappeared. When I tried to recover or load a saved game, the whole game just crashes. I removed all my mods and put them on my desktop but the issue is still there. I repaired the game and that didn't do anything either. What should I do?
