Apparently, this happens if you unistall a third-party Anti-virus software. But it is easy to fix it by following steps

1. Open Powershell with elevated (Admin) access

2. Run following command

Add-AppxPackage -Register -DisableDevelopmentMode “C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml”

That’s it. Done!
