Hi all, i am having trouble running a virus scan, my virus and protection is unable to launch.
I have recently gotten a lenovo ideapad gaming laptop, running windows 11 pro and ever since i can not launch virus and protection.

I have followed the below steps, however i am still stuck with the same issue,

1. Run SFC and DISM
   
2. Repair & Reset Windows Security
   
3. Restart Windows Security Service ( unable to restart, option is greyed out)
   
4. Check your Date and Time settings
   
5. Turn on Virus and threat protection settings ( unable to as it isnt in windows security panel)
   
6. Turn on Real-time protection ( same issue as above, it isnt available)
   
7. Uninstall any other third-party antivirus
   
8. Run a malware scan with ESET security
   
9. Fix: Windows Security Virus & Threat Protection missing using Local Group Policy Editor
   
   1. Computer Configuration\Administrative Templates\Windows components\Windows Security\Virus and threat protection
      
   2. Select “Not Configured” or Disabled to show the Virus & threat protection in Windows Security.
      
10. Using Registry Editor
    
    1. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender Security Center\Virus and threat protection
       
    2. Set the value to 0 to show. Or you can also delete “UILockdown” to show the Virus and threat protection.
       
11. Use PowerShell

Please could someone help me, i feel really compromised without the ability to access virus and protection settings.

Windows Security is not accessible in Windows 11 Home

I recently encountered an error and am unable to access Windows Security after resetting the Acer Predator Helios Neo 16 Laptop. When opening Windows Security, the app window is blank. When attempting the same with Virus & Threat Protection, I receive an error: 'Page not found - Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available. Contact the IT helpdesk for more information.

I checked the "C:\Windows\System32" path and its empty. Same for the group policy folder.
