I have the same issue, i've tried everyting even that link from EA it doesn't work because the sims 4 isn't on the list.
- Download the EA Anti-Cheat installer
- Run EAAntiCheat.Installer.exe as Administrator (right-click > Run as administrator).
- In the dropdown menu, select your game (e.g., Battlefield 2042, FC25, etc.).
- Click Repair to uninstall and reinstall the anti-cheat service for the game.
- Wait for the process to complete, then restart your PC and try launching the game again.
If repair doesn't fix the issue, proceed to uninstall/reinstall:
- Run the installer again.
- Select your game and choose Uninstall.
- Once uninstalled, reboot your PC and run the installer again.
- Select Install to reinstall a fresh copy of the anti-cheat.
- Restart your PC and launch the game.
