Game wont even launch before it crashes

CosmicPuddyKat​  If you have a newer HP gaming laptop (Victus or Omen) with an Intel processor, please try one of these workarounds:

• HELP! The Sims 4 crashes during launch or in the main menu | EA Forums - 12048779
• Game won’t launch | EA Forums - 4992631
• Managed to fix my problem where it crashes during launch after update | EA Forums - 4998584
• Disable the Intel iGPU
• Put the laptop in night mode

None of these works for everyone, but something almost always does, so keep trying the workarounds until you find one that lets you play.

If these don't help, or you have a different computer, please try playing in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.)  Don't add anything to the new folder yet; just start a new save and see how it runs, that is if you can get that far.

If you still can't play, 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.
