Hello,

When you're experiencing issues opening Start Menu, this article can help in resolving
the issue. Please follow all the suggested steps and report back to us if the issue would still persist. I also suggest that you run a scan using
Windows Defender Offline to be sure that your device is secured.
Go to Settings > Update & security > Windows Defender> Select Scan Offline. This would take around 15 minutes and restart your device.
To see the scan results:

• Select the Start button, then select Settings > Update & security > Windows Defender.
• On the History tab, select All detected items, then select View details. Any items detected by Windows Defender Offline
  will be listed as Offline in Detection source.

Update me if there are improvements.

 

Windows Defender isn't initializing.

Hi Abdul,

Sorry for the delayed reply. I suggest you to Set Windows Defender to Automatic - You can set the Windows Defender service to Automatic, Disabled or Manual. Setting it to automatic might solve the problem. Follow these
steps:

• Click Start > type services in the Search box > click Services in the Programs list.
• Search for Windows defender.
• Double-click Windows Defender, and click Automatic in the start-up box > click OK.

Also, follow the below mentioned steps and check:

• Open the Task manager. Here’s a tip: Press CTRL+Shift+ESC.
• Click File > Run New Task
• Make sure you have a check mark beside “Create this task with administrative privileges”
  
• Type CMD
• Type the following 2 commands at the CMD prompt:
  
  dism /online /cleanup-image /restorehealth
  
  sfc /scannow
