    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

Have you solved the problem? I have the same problem. I copied and pasted the command but it didn't work like you. MASA-0
