Fix 1 – Using Powershell disable development mode
1. Search Powershell in the windows 10 taskbar search.
2. Right click on the powershell icon and choose run as administrator.
3. Now, copy and paste the code given below and Hit Enter Key to execute the command.
Add-AppxPackage -Register -DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"
That’s it. Now, you will no more receive this error.
