vALE_mONGE1 Does a new save work? Please test for comparison's sake.
If not, please try playing in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.) Don't add anything to the new folder yet; just start a new save and see how it runs, that is if you can get that far.
I'm not saying you have to ditch your old save, only that it's best to get the game working in general first. If the new save works in the clean folder, you can copy your main save to that folder and try playing it.
If you still can't play your main sims, try using Load Game to play a different household within that save.
