Omg_its_Tayyyy AdielisXp If you still need help, try removing the saves folder from Documents > Electronic Arts > The Sims 4. If this fixes the issue, you're likely seeing this:
Crashes on Mainmenu | EA Forums - 12139111
atu27 If you still need help, please let me know whether this happens in a new save as well. If the new save is fine, try a different household within the same save. You don't need to save your progress; this is just for testing.
If the new save is affected too, please provide a dxdiag. Click 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 paper clip (Attachment) icon included with the other formatting buttons.
