Turn off Origin In-Game:
Open Origin, Select Origin > Application Settings > Origin In Game tab and click the on/off switch to disable Origin In Game. - This deactivates Origin In-Game, as it has been known to cause problems with games.
Restart the computer, to help the computer refresh itself, and try the the game again.
If you've recently tested your mods and custom content to make sure they're up to date with the latest game patch - August 16 2018.

You may need to clear your game cache and delete the localthumbcache.package from the Sims 4 folder to help with troubleshooting.
