Re: Sims 4 game will load but most mods are missing
@tenoddcats Just to be sure, you've enabled both custom content and mods, as in, both boxes are checked, within the game options? Please check in case one box has become or remained unchecked.
If that's not the issue, please set exceptions in your antivirus for Sims 4 and the EA App. There are different ways to do this with a third-party antivirus; here are a few examples:

If you only use Windows Defender, either disable Controlled Folder Access or set exceptions for the game and the App there.
