I’ve been trying to uninstall Sims 4 all day since it was taking so much of my storage and so I clicked uninstall but when the origin helper thing would pop up I would give it permission but after that it wouldn’t do anything at all
Can I ask if you're playing on PC or Mac?
Remember that you can always try to uninstall the game outside of Origin client, but the methods are different depending on what device are you using. I would also recommend to look into your account permissions. It's quite possible that you might not have admin rights on your PC or Mac to uninstall anything from it.
