If it's good, then continue testing the rest of the cc in small batches. Like no freezing, lag, weird/odd glitches. You must delete the game cache and delete the the localthumbcahche.package file after adding each batch, launch the game to test and play it to make sure everything is in working order. Replace CC in very small batches (say 5 files or less), starting with CC first. Removing the mods folder without deleting the localthumbcahche.package file from your The Sims 4 folder, also isn't enough of a test. Disabling or turning off both mod/cc options isn't enough of a test. Testing like this will help determine if it's a mod issue, cc issue or a vanilla game issue. Quit without saving so that the game will go back to how it looks with CC. If there is no crashing/freezing then you know it was a Mod or some CC causing the issue. Start the 'problem game' to try replicating the issue again. Repair Game: Click Sims 4 > Manage > Repair. Step 1: Move the Mods folder to the desktop, Delete Game Cache Files and delete the localthumbcache.package file from The Sims 4 folder, in the Documents folder.

If the game works when the Mods folder is removed, then one or more of the mods and/or custom content has become outdated and will need to be removed or replaced. *Note:* Custom content can become outdated with most new game patches.
