Unable to select traits in CAS

Hi, 

My traits are  not showing up in CAS. At first I thought this was caused by a broken mod, but I’ve since ruled that out.

So far, I have removed all mods and custom content, deleted the localthumbcache.package, avatarcache.package, onlinethumbnailcache, and the cachestr folder, deleted the entire Sims 4 folder from Electronic Arts, and fully uninstalled and reinstalled the game.

The game works perfectly when I launch only the base game. However, once I reinstall my expansion, game, and stuff packs, the issue returns. Because of this, I don’t believe custom content is the cause.

For reference, these are the packs I installed after confirming the base game was working correctly:

Seasons, Enchanted by Nature, Get Together, Business and Hobbies, Lovestruck, Werewolves, Vampires, Life and Death, Island Living, Growing Together, Realm of Magic, Snowy Escape, Cats and Dogs, City Living, Parenthood, Cottage Living, Eco Lifestyle, My Wedding Stories, Spa Day, Tiny Living, Crystal Creations, Backyard Stuff, Movie Night, Cozy Bistro, Comfy Gamer, Kids Room, Paranormal, My First Pet, Laundry Day, Home Chef Hustle.

Thanks in advance for any insight or troubleshooting advice.
