Hey tiesewllms, that's pretty odd. Are you using any Mods or CC?
If yes, please make sure to uninstall all of those at the moment.
As a first troubleshooting step, I always recommend backing up the Sims 4 folder and resetting the game.
If that didn't work, you might try uninstalling and reinstalling the game.
As best practice, another good thing to do is to perform a clean install of your graphics drivers.
When you install those, you should have an option to do a complete/custom installation, and then you should be able to select the option for a clean install! It might vary depending on the graphics card manufacturer.
I'll also leave two useful guides that might help you fix the issue:
Troubleshoot PC, PlayStation, and Xbox crashing or freezing, & Games that won't download, install, or load in the EA app
Keep us posted and let us know if the issue still persists!
