Re: Sims 4 game won't launch after update
@HookedOnSims Please try repairing the game: open your EA App game library, click Sims 4, and select Manage > Repair.
If the repair goes through, try to play. If it doesn't, please uninstall the EA App with Revo Uninstaller (the free version is fine), restart your computer, reinstall the App, and try again to repair.
