I am not finding any reports on this issue and there's no mention of what troubleshooting was done, so please forgive the repeat suggestions.
1. Does traveling to a different lot with current family and then back again help?
2. Try using the cheats in a different household to see if that helps.
3. Fully exit game and Origin and then reload Origin and the game to see if that helps.
4. Repairing the game may help. - In Origin > Games Library > Right-click on Sims 4 and select Repair.
5. Regardless if mods are installed, delete the localthumbcache.package from inside the Sims 4 folder and try again. This helps with troubleshooting.
