Windows Security opening to the grey screen with the logo then closing a minute later

Question

I attempt to open the Windows security app, only to be met with the grey loading screen with the logo in the centre (as shown in the attached image), it then closes itself approximately a minute later. Is there any way to fix this?

Hi, I'm Bernard. I'm happy to help!

This happens when there is a corrupted file in the Windows Defender folder or a reconfiguration is needed. First, you need to check if you have a work or school account:

Open Settings> Click Accounts> Click Access work or school, then disconnect the account there. If you have no account or have already disconnected and you have the same issue, follow the steps below:

Note: Before doing the steps, I suggest completely uninstalling the third-party antivirus first.

Method 1. Repair Windows apps and Windows Defender:

Open Terminal (Admin) or Windows PowerShell(Admin) (Press Windows key + X then click Terminal(Admin))

Copy, paste, and enter the command below:

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Restart the PC and check

Method 2. Reinstall Windows Defender

Open the registry, then go to

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Then delete the Windows Defender folder, restart the PC, and recheck it.

Note: If the issue persists, a system repair might be necessary.
