Sims 4 Keeps Crashing

Recently came back to the Sims 4 on a new laptop running Windows 11 after a long time away, and it's just been one headache after another; while the game seems to run fine with zero CC/mods, as soon as I begin to install them, the game starts crashing all the time. 

• Sometimes it crashes at the initial "THE SIMS 4" screen
• Sometimes it crashes when I'm resuming a game
• Sometimes it crashes when I'm switching from live to build mode
• Sometimes it crashes when building a new lot
• sometimes it just crashes in the middle of nothing at all happening

Bottom line, the game becomes completely unstable. Script mods - ones that are supposed to be up to date with the current game version - make the game near unplayable, while custom content like clothing, furniture, etc. only seem to make the game crash some of the time.

Worse still, once the crashes start, it doesn't seem to matter what I do or remove, they get less frequent but never stop again entirely unless I do a completely clean uninstall/reinstall (including deleting registry keys) of the game, even when the mods are gone, I've deleted the Electronic Arts/The Sims 4 folder, and/or I've repaired the game. Running on DX9 vs DX11 seems to be slightly more stable, but it brings the crashes down to like 40% vs. DX11's 50% crash chance.

I'm really at my wit's end; I've done every single thing that's already been recommended. Clean reinstalls, factory resets, even reinstallations of the EA app, and nothing helps. I feel like there's got to be an obvious solution I'm missing, but can't seem to find anything that fixes the problem. I've attached the lastCrash.txt from the most recent crash in case anyone can make sense of it.

EDIT: It's now gotten to the point where the game is crashing on a fresh install, no mods, no CC, no nothing. I can get into the game, but it always crashes about 30 seconds or so after I start playing. This is nuts.
