@Amy1218 This is a problem with the EA App, not just for Sims 4 but for most if not all games. I don't know whether it's a bug or just poor design, but either way, it's how the App works right now.
One potential way around the problem is repairing the game: open your game library, click Sims 4, and select Manage > Repair.
If that doesn't help, then you'll need to clear more space, which would be best for the overall health of your computer anyway; or uninstall and reinstall the game.
@puzzlezaddict Repairing the game worked for me! Thanks so much! I can finally play the game again! 😃
