Hello,

Has anyone experienced this? Running Windows 10 Enterprise 1803. After enabling Application Guard, regular Edge breaks. Opens then closes. Unable to resolve this issue.

Same issue for me, I am still researching. Would be good if you indicated if you had a resolution.

Nope. Even worked with Microsoft Support. Could not determine the issue. So I had to refresh again and not enroll the device.

  Sorry, I forgot to post back, however I have found the solution for this issue. The same issue occurs when applying a software restriction policy. And found this great article -

  This is the solution:
  
  1. Get-AppXPackage -Name Microsoft.MicrosoftEdge | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml” -Verbose}
  
  2. reg add “HKCU\Software\Microsoft\Internet Explorer\Spartan” /v RAC_LaunchFlags /t REG_DWORD /d 1 /f
  
  No reboot required.
