You will need to find all broken CC items and Mods (if you use Mods) and check with the creators of them to see if they have versions of them that work with the game update that occurred this week. Unfortunately, the more CC items you have, the more difficult it will be to find which one (or ones) are causing problems.
If you are going to use CC or Mods you will have to do maintenance on them regularly. we recently have had a game patch so one or more of your CC eye colors have become outdated/broken.Information, Guides and Announcements for the EA app.
