CAS not loading ?

CAS on my sims 4 game is will not load. The game itself loads fine, but when I go to edit sims nothing loads. If I try to start a new game CAS won’t load. It’s stuck on the loading screen when in gameplay. And it’s stuck on the white screen when making a new game. I do have mods but I have them updated. Seems like this is the only thing not loading. Anyone know what I can try to fix it?
