'Application not responding' when trying to open the Sims 4

My Sims 4 won't open. I know it's not broken CC because I recently updated them... It worked when CC was disabled but I tried repairing everything but it won't work... I remember asking EA support a few months ago and something about clearing cache and something more complicated worked but I can't remember it for the life of me and now I'm stuck :( PS. I updated my game just now and I suspect that might've been the reason idk tho.
