Windows 10: Windows defender wont open anywhere

My windows defender yesterday popped up with a notification saying that there was something on my browser that needed a fix when i clicked on my defender to open it and resolve the problem it dosen't open. I tried opening it through the settings but it just wont open no matter where, it says that it's running but it wont open. I have tried dism scans and sfc scans, powershell resets and reinstalls but it said that there was no file such as AppxPackage im assuming this is the windows defender app and SecHealthUI is missing too. Does someone know a fix for this.

:)

Hi Ian,

Thanks for posting your query on Microsoft Community.

This issue might occur if you have set any task scheduler for Windows Defender.

I suggest you to delete the task for Windows defender and check if it helps.

Follow the below steps:

• 
  Search and open Schedule tasks.
  
• 
  In the left-hand menu, open the Task Scheduler Library, then select
  Microsoft >Windows >Windows Defender.
  
• 
  Double-click Windows Defender Scheduled Scan.
  
• 
  Select the Triggers panel, then select Delete.
