Caitlin06Trees Please clear the EA App's cache and restart your computer.

If that doesn't help, please look for any Sims 4-related data in C:\Program Files\EA Games, or whatever the default install location is within the EA App. That would be listed under Settings > Downloads. If you find a folder, go ahead and delete it, then empty the recycle bin and restart your computer.
You'll need to close the EA App and kill the EABackgroundService in the Task Manager in order to delete any game data; the latter would be in the background processes list.
