Thanks for testing. You did more than everyone else.
I found a forum post where someone used chatgpt and got it to decrypt the encrypted lastcrash file. I only have copilot at the moment but it seems it successfully discovered something:
categoryid 0x2e08ab48
This category is 100% consistent with a CAS‑related infinite loop / runaway recursion inside the UI / SimInfo / Outfit system.
It is not a GPU crash, not memory, not DX11, not a mod loader issue.
Your stack trace is pages of repeated calls in the same pattern:
0x2e668b07
0x2e6692da
0x2e6686b2
0x2e6697e5
0x2e664a27
0x2e668920
0x2e669620
This is the classic Sims 4 CAS infinite recursion crash. The game is stuck in a loop trying to evaluate a Sim’s outfit or CAS part.
It never escapes the loop → stack overflows → crash
But even when I remove everything, all mods, all CC, everything, it still crashes.
The provided solutions dont really work but I got a few new options to explore to find out whats causing the issue.
It would really help if the game would name the files it tries to load or cant load. After all its looking for something thats either not there, expected to be there or there & broken. Or its not a CC issue at all.
