Using the Sims 4 Tray Importer would be the easiest way to find the broken CC. I recommend saving your sim to your library and then closing your game. This will make your sim family first on the list of trays when you open the importer. The link to the program is included in the instructions. Sorry I edited it for a simpler tutorial. It is a pretty good guess that your broken CC is the glasses your Sim is wearing. With this mod you can identify them, it will even provide a link to the site of Origin so you can check if they have been updated or if you are missing something.
