    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

JianYu this solution doesn't work for me

tried other solutions like https://www.thewindowsclub.com/windows-security-not-opening-or-working

 

except for only reinstallation on my side. Do you have any other solution? I bit doubtful windows defender then install 3rd party  internet security ie, Kaspersky
