Re: Sims 4 code error 111
It appears this is a common error due to outdated mods and custom content.
If playing with mods and custom content, move your mods folder to the desktop, delete the game cache and the localthumbcache.package from the Sims 4 folder to help with troubleshooting.
How to Delete Cache Files - https://sims4.crinrict.com/en/2014/09/delete-cache-files/
Deleting the cache files will remove all traces of mods and custom content that were tied to your game.
Launch the game again and try a new save to test - without the mods folder. If it loads and plays okay, it may be that some of the mods/cc have become outdated.
Testing like this will help determine if it's a mod issue, cc issue or a vanilla game issue. - Disabling or turning off both mod/cc options isn't enough of a test.
To fix mods and custom content 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.

Custom content can become outdated with most new game patches. If the game works when the Mods folder is removed, then one or more of the mods and/or custom content has become outdated and will need to be removed or replaced.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.
