Re: Sims 4 Game Not Opening
If the game works without your Mods then the issue is one or more of your Mods. 3rd party content must be compatible with the current patch level of the game. Mods can, and frequently do, break after the game is patched. Check with the creator.
To test the CC/Mods, move out your Mods folder to the desktop and trash the localthumbcache.package file. Start the game to check it will load then quit without saving. Move your CC back in in batches, loading the game after each batch to see if it still works. When it stops working you know there is dodgy CC in that last batch. Move out that batch and test each piece one by one until your game stops working again. It's laborious but the only way to check all your CC.
