@clyd234 Jumping in as a fellow Mac user and helper. Please do not ever use any 3rd party apps that claim to "clean" your Mac of unnecessary app or system files. They often cause more damage by removing important files and can destabilise the operating system, resulting in the user needing to reinstall apps and even the OS in some instances. Apple's own support forums are full of very experienced Mac users telling people never to use them 🙂
Uninstalling EA App will not fix your issue here and is irrelevant. Game updates frequently break Mods and CC. Next time it happens follow these Mac specific instructions to try a clean game
