ea app black screen

Ever since the new pack came out and the couple updates, my game and ea app have been so broken. The ea app has been opening to a blank black screen somewhat regularly, I used to be able to just redownload the app and then it would work but now that isn't working either. When I am actually able to get into the game, my sims bug out, idling instead of completing tasks with the task still queued, considerable lag, and the occaisonal crash. I'm not tech savvy and I know my Macbook is old (2018) but this wasn't a problem until recently.

EDIT: Game as of right now is unplayable, sims stuck and I can't switch between sims in the household. I pause the game and it switches to them, unpause and I'm unable to make them do any tasks, they won't even queue it. I can't even try to go to a new household or go to manage worlds because if I leave the lot whether that be to travel or just save and exit the game get stuck on the loading screen and ends up not responding.

Please someone help me, this is incredibly frustrating.

What I've done so far:

• Re-installed the EA app
• Restart my laptop
• Lowered all graphics to low
• Deleted all mods and CC
