Many users complained that when they are trying to open windows security, they get an message saying You’ll need a new app to open this. When they click the OK or Next option on the pop up, the pop window goes away. If you are also a victim of this bug, here is a working fix to solve this problem.
Fix 1 – Using Powershell disable development mode
1. Search Powershell in the windows 10 taskbar search.
2. Right click on the powershell icon and choose run as administrator.
3. Now, copy and paste the code given below and Hit Enter Key to execute the command.
Add-AppxPackage -Register -DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"
That’s it. Now, you will no more receive this error.
