    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

I've tried the resetting, re-installing, and other tips in this thread and I still cannot launch the Security App. I just get a blank window with the Security App icon in the middle.
I have Acronis Cyber Protect Home Office and have disabled the protection but the situation is still the same.
