Sims 4 CAS Screen black and will not show/load families

Ever since the August update my Sims 4 game has been broken. The game will launch but cannot load any actual sims? If I try to load a saved game the sims in their households won't show/load, and if I try to go into a household the loading screen will play for a couple of minutes and then freeze. If I try to start a new game CAS is just a black screen with the aspirations/traits/clothing options available but it won't show the sim.

I have already tried repairing the game, uninstalling and reinstalling both ea and sims 4, deleting the mods and cache folders (though I do not and have never used mods). I am using a computer with windows 7 but the sims 4 have been working great for over a year now. Does anyone know how to fix this?

I attached the DXdiag if that helps.
