Re: Sims 4 not working after update? Help?
@KRP2001 Try repairing the game in Steam: open your game library, right-click on the Sims 4 tile, and select Properties > Local files > Verify integrity of the game files.
If that doesn't help, try deleting the file in your error message and repairing again. The repair should download a fresh copy of the file.
If that doesn't help either, please let me know what antivirus you use.
