I realized something weird was up. But no worries, thank you for taking the time to respond!!
My mod list is pretty massive but I will try my best to list out everything I can. As for what was happening on screen on the time of the crash, nothing big really. I had a family of 4 sims, all young adults, wandering around their house. I had one sim queued up to fix a shower and a toilet, one sim was watching TV, another was about to cook, and the fourth I think was simply walking around not doing anything. That's what makes it so odd to me as it happened seemingly out of nowhere.
Now as for mods, I think my two major ones are MCCC and one made by Turbodriver. Both of them are up to date and I double checked after the crash. Turbodriver's mod has a bunch of addons (creators include: E404, erplederp, Azmodan, CherryPie, Wildguy, Anarcis, Amra72, mike24, lupobianco, MotherlodeSims, Nandong, and Yrsa), simple animations that none of which were in use at the time of the crash.
Other mods include a handful of mods by LittleMsSam: AutoEmployee, Auto Thermostat, Better Familiars, Can I Come Over, Dress Code Lot trait, Entrance Fee Lot trait, Force to Leave, Hire Certain Sims, Improved Practical Spells, More Away Actions, More Best Friends, More Buyable Venues, More Fun Stuff, More Holiday Icons, More Serving Options, Online Learning System, Preferences Lot Trait, Retail Overhaul, SimDa Dating App, and Where Are You. All of these I double checked and only a few needed updates. I have not tested the game after updating them yet.
I have 2 mods by Sacrificial Mods: Sim Torments and Passionate Romance. With accompanying props and addons. This one I updated a month ago before the crash.
I have 2 other script mods called Scarlet Sim City Loans and Scumbumbo Teleport Any Sim. I have not checked if these needed updates. I used to have career mods but I uninstalled those some days ago.
Lastly are my massive amounts of Clothes, hair, and skintones mods. I recently updated a few of the broken skintones that wouldn't show up in CAS, not sure if that would have anything to do with it. But I have way too many of these mods that I am unsure if I can properly list them all without taking an hour or two to do it. But as I mentioned, these mods are all clothing, hair, or skintones.
