Sims 4 crashing after Sept. 2024 update when I go into build/buy

I've been having a similar issue since updating!

I can enter build mode just fine, but once I go to leave suddenly I can't click on anything other than the save menu and manage worlds, but saving and/or going to manage worlds just breaks it further, and I have no choice but to exit. Plus, the Grim's weekly event menu isn't showing up, but I can still do the actions and get the rewards (thanks to the R/Sims4 subreddit for telling me what to do!)

I have mods (MCCC & UI Cheats) and CC (only CAS items), all of which are up to date.
