sims 4 crashing on loading screen/won’t launch

laneybird81​  If you haven't already, 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.

If you get another crash, 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.

Unfortunately the game will not even load up far enough for me to open any save files or start a new one. It crashes before I get to the main menu. 

I also have tried deleting the entire electronic arts folder and reinstalling the game. It still will not launch with a clean user folder. 

laneybird81​  The InPageErrors listed in your dxdiag point to an issue with your computer's page file, which is space on the system drive allocated for spillover data that would normally be in RAM but doesn't fit.  This could be a problem with the drive or the RAM, or just an issue with the page file itself.  Since the last possibility is the easiest to test, let's start there.

Please delete the entire page file, restart your computer, and allow Windows to rebuild it.  You can do so by setting the minimum and maximum sizes of the page file to zero, as described here (option three):

Restart your computer, then go back to allowing Windows to manage the page file size.  Restart again and see whether you can play.

If you still can't load the game, please test your SSD using the chkdsk command.  Click Windows key-X and choose "PowerShell (Administrator)" or "Terminal (Administrator)," whichever you see.  Enter this command in the window:

chkdsk /f /r c:

You'll be asked to allow a restart; choose Yes.  The scan may take a while (possibly a couple hours), so you'll want to do something else while it runs.  When it's done, here's how you can find the report:

I'd like to look it over, so please attach it to your reply.
