Specific sims causing crashes

So, recently I've been having issues with a specific sims 4 households of mine crashing my game.

Whenever I try to load into the household, it crashes. I can still place them in a world and it'll work fine, but can't visit them with another sim or play them at all. I've tried to work around it, trimmed hundreds of my male cc, moved my mods folder to desktop to make a new one, repaired the game through Origin, got rid of all my ts4script files, and nothing.

The weirdest part is that ALL 3 of the sims in the household seem to be game-breaking, I've tried isolating them with new random sims and the game continues to crash. I've made a ton of new saves in completely fresh worlds and it still crashes no matter what. I can edit them with no issues whatsoever in CAS.

My game runs completely fine all other times, no trouble with lag or random crashes mid-game, no issues with new save games. It's only this household and it seems like all the saves they touch break somewhat. Originally I had them in a world with a bunch of custom sims, I've tested and all other households load in without issue. The household successfully loads if I'm playing completely vanilla with no mods or custom content, so I tried slowly adding in CC by around 300 or so each time and it seemed fine. However, once everything was back in in the household began crashing again. The thing is, all the CC they're wearing are items I use on basically all my other male sims, hairs, tattoos, etc. So I can't be sure if the issue is with a few broken pieces of CC or what.

I know I should most likely just abandon them and recreate them, but it's kinda concerning to me that I just have no idea what's going on. I really don't want it happening again with other households of mine.
