Sims 4 Crashing after update 9/18/24

8369232af5024943  Do you have any Razer apps installed?  The clean boot should have disabled them, but I vaguely remember that that wasn't enough for at least a couple of players when the associated problem first surfaced.  Point is, uninstall anything from Razer and try again.

If that doesn't work, try the clean boot again but in a new admin Windows account.  Make it local, as in, don't link it to your Microsoft account.  You'll be able to launch Sims 4 without reinstalling anything, but your saves and other user data won't be available.  That's fine and can be addressed later.

If this doesn't help either, please post a new dxdiag.

I do want to mention that switching to DirectX 9 mode might get around the issue.  It's not a very-long-term fix since we don't know how long Sims 4 will even have DX9 mode, but you should be able to play fine for now.  DX9 is a check box in the graphics options, to the right of post processing.
