Sims 4 crashing after Sept. 2024 update when I go into build/buy

Same for me, and I have no mods or CC

SigmanBaker  If you're using the Off the Grid lot challenge, please remove it in Build mode.

Otherwise, please create your own thread describing the context of the crashes: when they happen, what you see on-screen, etc.  Please also provide a dxdiag.  Hit Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the camera (Insert Media) icon included with the other formatting buttons.

I am going to try this out! Hopefully it helps. Thank you for the tip!!

Same here, i don't find a solution, mines crash when i go out of Cas

Bhaler  If you have any mods or custom content, please remove the entire Mods folder and delete localthumbcache.package.  You don't need to save your progress; this is just for testing.

If that doesn't help, please provide a dxdiag.  Hit Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the camera (Insert Media) icon included with the other formatting buttons.

My game crashes every time I go into build mode but only when its a household I play with. Ive tried everything but getting rid of mods and cc cause I just don't want to do that and have to figure out each one. I did the Dxdiag and nothing came up so idk what to do. pls help

agentsmellis00  Sorry for the late reply.  I'm not sure how I missed your post the first time around, but this site is weird about sort order sometimes.

At any rate, your dxdiag makes the issue obvious: it's an incompatibility between your graphics chip, or more specifically the chip and driver combined, and Sims 4's DirectX 9 mode.  So force the game to use DX11 mode instead.  Open the EA App, click Sims 4 > Manage > View properties, and add -dx11 to the command line box.
