Sims Keep Freezing and I feel like I've done everything!!

I ended up saving the household and the lot to my library from my old save file and bringing it to a different save (the new one that I started in my blank game). Using the same exact sims and same exact house, the issue went away- just uploaded from my library after saving it myself (so it technically isn't the exact same household).
The pausing/freezing isn't an issue with this clean Sims 4 folder, although when I transferred that old save over and tried to play it, it was.

No big deal though, as long as I could play and I couldn't tell the difference I don't mind. I guess it was something wrong with that save specifically. I had been using it for a while and never made new ones when I moved onto new households.

I also moved most of my mods over except the scripts, and reinstalled the only few script mods I wanted, so I know they're up to date now if they weren't previously. After adding all my cc back, that didn't cause any issue.

Thank you so much for your help, as I wouldn't have even been able to move my stuff over and play the game without figuring out how to get a clean slate.
