sims stuck and unresponsive

Hi @kaylaax95. Unfortunately, this does sound a lot like a problem with a mod or CC that's not compatible with the game anymore.

You can test that to see if it's the case. After exiting Sims 4, drag your Mods folder to your desktop. Then delete the file called localthumbcache from Document > Electronic Arts > The Sims 4. If you think you might accidentally forget to exit without saving after testing, copy your Saves folder to your desktop too, to back it up. Now open Sims 4 and see if you still have the problem. If that fixed it, you can start the process of figuring out what from your Mods folder was causing it -- you don't have to lose everything!

To find out what mod/CC is causing the problem, you can start by consulting lists of known broken mods (my current one is on the Sims Forums and is linked from this post. Check updates too!

If you have a lot of mods and CC and some of it is old, you might have to do a 50-50 of your Mods folder to find what the problem mod/CC is. This means organizing the files there into bite-size batches and testing one batch at a time. For each test, delete localthumbcache, then put only that batch in Mods. If your game behaves properly and your Sims can do what you want them do, exit without saving, set that batch aside as "cleared" and delete localthumbcache again. If it doesn't behave as you expect, take out half the batch (that's the "50-50") and see if you're closer to finding the culprit. Remember to delete localthumbcache each time. You'll find some 50-50 method tutorials online too. Once you isolate the file, you can go find out if there's an updated version.
