Windows Defender on Windows 11 stuck on logo and closes after a few minutes

First, a quick reassurance about that service: the Windows Defender Advanced Threat Protection Service (service name: Sense) is actually an enterprise feature meant for corporate environments (Microsoft Defender for Endpoint). On a standard personal PC, this service is supposed to be stopped, and trying to start it manually will always throw "Error 1067" because the machine isn't onboarded to an enterprise network. You can safely ignore this, as it's completely normal.

As the clean boot didn't help, please create a new local account with administrator privileges.

To add the new user, follow the instructions in "Add a user account". Create the user without a Microsoft account.

To give administrator privileges to the new user, follow the instructions in "Configure a user as an administrator".

Then, log out of the current user and log into the new user. On the new user, see if Windows Security opens correctly.

Please let me know the result.

Feel free to ask any questions you may have.

I've added a new user and made it an administrator, and nothing changed when launching windows security.

Thanks for the clarification.

Since the app shows exactly the same behavior on a brand-new administrator account, we now know this is a system-wide issue, meaning the application is unregistered or dropped from the core Windows application database.

When you performed the In-place upgrade, Windows completely refreshed your core system files under the System32 directory. This means the physical files for the Windows Security interface should be sitting on your drive, but the system simply doesn't know they are there because it's missing the registry database entry to launch them.

To fix this system-wide issue without guessing your exact folder structure or version numbers, you can use a smart PowerShell command. This command will automatically scan your local security health directory, locate the raw installation manifests, and force Windows to re-register the UI dashboard directly from the physical path.

Please try the following:

1. Right-click the Start Menu and select Terminal (Admin) or PowerShell (Admin);
2. Copy and paste the following command into the window and press Enter:

Get-ChildItem -Path "C:\Windows\System32\SecurityHealth" -Recurse -Filter "AppXManifest.xml" | ForEach-Object { Add-AppxPackage -DisableDevelopmentMode -Register $_.FullName }

3. Once the command executes (you should see a brief green deployment progress bar flash at the top of the window), restart your computer (using the Restart option, not Shutdown).

Please let me know how it goes.

Feel free to ask any questions you may have.

When i inputed the command, the deployment progressbar didnt show up. I tried restarting my pc afterwards and still nothing changed

The fact that the progress bar did not appear might mean that the PowerShell command couldn't find any installation files inside your security directory. Even though you did an In-place upgrade, a known glitch in certain Windows 11 upgrade paths can cause the system to completely drop or leave this specific directory empty.

Since the files are physically missing or corrupted on your drive, let's try downloading the official standalone installer directly from Microsoft's update servers to regenerate the components and force-register the Windows Security app wrapper.

Please follow these steps:

1 = Download the official Security Health setup:

1. Click the official direct link below from the Microsoft Windows Update catalog to download the standalone installer package:

https://catalog.s.download.windowsupdate.com/c/msdownload/update/software/defu/2024/02/securityhealthsetup_e16941e14861a6d24750ecdf05c548189b33182a.exe

2. Save the file to your Downloads folder or Desktop.

2 = Run the installer:

1. Locate the downloaded file (securityhealthsetup_...exe).
2. Right-click on it and select "Run as administrator".
3. You should see a couple of black command prompt windows flash briefly on your screen and disappear. This indicates that the utility is actively expanding and re-registering the application dashboard globally.
4. Wait about 2 minutes, then restart your computer (using the Restart option, not Shutdown).

Once you log back in, try launching the Windows Security app again.

Please let me know how it goes.

Feel free to ask any questions you may have.

I ran the exe as admin, then waited a couple of minutes and restarted. Nothing changed
