EA App failing to launch Sims 4

While trying to launch The Sims 4, it crashes because the EA App doesn't work properly for whatever reason. And I can't uninstall it because somehow the file for uninstalling it doesn't exist.

I have this game on both Epic and Steam, and checking file integrity on Steam doesn't seem to fix anything. The EA App itself won't open because any shortcuts I do find don't work.

A factory reset is the last resort, so if anyone's got solutions, I would be open to them.
