Sims 4 doesnt launch, does appear in taskmanager.

@JustTim51955  That just looks like a generic Windows update, something to Game Mode or Game Bar that you can ignore.  I still think this is a case of the game being blocked, so the next step is a clean uninstall and reinstall of Sims 4:

• If you have any saves you want to preserve in the original account, put them in a folder that does NOT contain "Sims 4" in its name.
• Switch back the new Windows account.
• Download Revo Uninstaller (the free version is fine) from here.
• Launch Revo, select Sims 4 from the list, and click Uninstall.
• Cancel the system restore point; you don't need it.
• Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
• Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
• Close Revo, and restart your computer.

For the EA App:

• Launch Revo, select the App, and click Uninstall.
• Cancel the system restore point.
• The EA App may open a window.  Click Uninstall, then in the Revo window, click Moderate under Scanning modes, and click Scan.
• Revo will present a list of registry entries.  Click Select All, then Delete: you don't need or want to preserve these entries.
• For the leftover files and folders, click Select All, review the list and deselect anything you'd like to keep (this is unlikely, but it's worth checking), click Delete, and you're done.
• Close Revo, and restart your computer.

Install the EA App, then create a new folder into which you'll install Sims 4.  The folder should be on the root level of the drive of your choice, for example C:\Games is fine, but not C:\Program Files\Games.  Please continue to test in the new Windows account just to be as thorough as possible.
