Hello,Suggest try the following steps:
- Open PowerShell by using Administrator rights
- Copy and paste Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage to the PowerShell window and press enter
- Close the PowerShell and retry

Ran "Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage" in Windows PowerShell as Administrator and it worked!
Thank you!

This worked for me. "Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage".
First time I tried it in the PowerShell, I copied too much text. I also copied "in the window". This will not work. But now all is good. Thanks for all the help!!
