Re: Error de4ee14f:29f00e76:00000000:4b0d852b
@killaki19 As a test, please remove all your mods, as in, move the Mods folder to the desktop and delete localthumbcache.package. If this works, you can start adding back mods and see which ones cause this issue.
If that doesn't help, move the entire Sims 4 folder out of Documents\Electronic Arts and onto the desktop and test again. This will temporarily remove all your user content (saves, saved Tray items, etc.), but you can put those pack later, once the game is working again. If you still get the same error, run a repair: open your Origin game library, right-click on the Sims 4 icon, and select Repair.
