There's no chance that that much CC isn't impacting your game. It's also very likely that it includes duplicates and broken content by now. I highly advise starting with a fresh user folder and re-adding CC gradually with some method.
Here's how to create a new folder:
- Drag The Sims 4 folder from Documents > Electronic Arts to your desktop.
- Start the game.
- Reset your Options.
- Start a new save for testing. Your old saves will be safe on your desktop till you need them.
- Play the new save for a while to see if you have crashing problems.
Now that you have a working game, you can start putting back CC, but less of it, and organized to stop ending up with as many new problems later.
Here's some ways to cut your CC quantity down:
- Set up folders in the new Mods folder by creator. This will help you remove duplicate files.
- Don't move back any zip or rar files. The game doesn't like those.
- Hair from before mid-2021 is missing the colors Maxis added then.
- Consider just deleting files you can't identify by creator at all.
- Use Sims 4 Studio (which has a new update) to look through CC and delete things you simply never use. They're taking up space that causes problems.
Here's how to find broken files while you add things back:
- Have a subfolder called NEW so you know what's in your current, untested-in-game batch.
- Once a bunch of files are there, play for a while to see if you have crashing.
- If you do, use the 50-50 on those files to find what's causing it.
- If you don't, you can move those files to their better homes and start with an empty "NEW" for the next batch.
Personally, this is what I think you should do: Start from scratch. Why? Because it's going to be a nightmare to sort through all that CC. Instead:
- Move Saves to your desktop unless you're willing to redress all your Sims and redecorate all their homes.
- Move Tray to your desktop if you want to preserve previous households and builds you saved to your Library. If it's a huge folder don't copy it back later. Leave it out of the game. You can put it back temporarily if you need access to those.
- Delete The Sims 4 folder from Documents > Electronic Arts
- Start the game and reset your Options
- Go CC hunting, but with some new rules: Don't download other users' folders of CC (this leads to crazy numbers of duplicates). Make subfolders by creator name so you can find files later when they're reported broken or updated, and to help you avoid having duplicates. Don't download "might use it someday maybe" CC; download "will definitely use it" CC>
