Windows 11 - Windows Security App won't open and no solution works

Hello. I've noticed that I can't open the Windows Security App no matter what. When I try to open Windows Security or even the settings related to it in any way, the window freezes and it won't open. I tried a few solutions already posted in this forum, such as

  1. Repairing and resetting Windows Security through "Apps" in the settings

  2. Reinstalling Windows Security through the wizard inside System32

  3. Reinstalling Windows Security through the command prompt

  4. Running the command "DISM /online /cleanup-image /scanhealth" and "sfc /scannow"

  5. Using PowerShell in admin mode to run the command "Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage"

  6. Properly exiting the command prompts and restarting my PC every time I do the previous steps

After doing all of these steps in every possible order and running every Update/Repair wizard I could find, the issue remains the same. I would appreciate any kind of help. Thanks in advance

Hello Emre Faruk Küçük

Welcome to Microsoft Community.

Regarding to your information I assume that you have some issues on Windows Security.

It seems that you have already completed most of the troubleshooting steps for Windows Security, but none of them have worked.

In this case, you may want to consider whether system file corruption is causing your current problem.

In this case, it is recommended that you perform an In-Place Upgrade directly through the ISO to see if it can fix the problem

In-place upgrade which will refresh your Windows files and operating system without removing files or applications.

That being said, we always recommend that if you have important data, you should back it up before making large system changes.

If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides:

If there is anything not clear, please do not hesitate to let me know.
