Are you able to restart the game?  If you do restart does it come back?

If playing with mods and custom content, move your mods folder to the desktop, clear your game cache and delete the localthumbcache.package from the Sims 4 folder to help with troubleshooting.

Try playing the game again to test without the mods folder. If it loads okay, it may be that some of the mods/cc have become outdated.

How to Delete Cache Files

Custom content can become outdated with most new game patches. If the game works when the Mods folder is removed, then one or more of the mods and/or custom content has become outdated and will need to be removed or replaced. EA/Maxis aren't responsible for broken mods/cc. It's up to the creators to fix.

Disabling or turning off both mod/cc options isn't enough of a test.

Try the 50/50 method:

1. Move all the mods and cc out into a temporary folder on the desktop.
2. Move a few files back at a time. Load the game to make sure it loads and everything is good.
3. Delete the localthumbcache.package from the Sims 4 folder.
4. Repeat steps 1 - 3 till there is no more files to check.

** While your testing, don't save the game. If you find any problems, delete the mod or custom content file.

If you've already been through your mods folder and cleared the game cache, try repairing the game.

Repair Game:
In Origin > Games Library, right-click on Sims 4 and select Repair.

I’ve tried all of those and it still doesn’t work
