Sims 4 Won't Launch on Windows 11

@honeyybucket  All the errors in your dxdiag are from failed Windows updates, so it's best to clean those up first.  Please run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

For the Sims 4 issues, please try playing in a clean user folder.  Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, if it launches, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.

If that doesn't help, let me know what you see when you try to launch the game, for example an error message or a brief black screen.  Please also look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of your most recent attempt to launch Sims 4, specifically after you've done the steps I listed.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.

@puzzlezaddictI meant to do this and reply much sooner, but I was traveling.
I completed the updates and the scans, when the sfc /scannow completed, it gave me this message: "Windows Resource Protection did not find any integrity violations."

I moved my Sims 4 folder out of Documents > Electronic Arts and managed to launch the game and play in live mode with a clean user folder. I checked on perfmon /rel and there were no errors.

Hi, I've done everything you've suggested here. All other system checks found nothing wrong. The reliability monitor response was: The program TS4_DX9_x64.exe version 1.115.253.1020 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel. I would greatly appreciate further instructions.

Ralana2727​  That means that this error still happens when you remove the Sims 4 folder from Documents > Electronic Arts?  I just want to be sure that you didn't remove it and put it back, or remove it but OneDrive redownloaded it, or anything else that would complicate the process.

If the game still doesn't work with this folder confirmed removed, 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.

Please also describe the issue you're seeing in more detail, for example does the game crash or freeze while loading, or after you've been playing a while (and in what context), do you get any error codes, etc.?
