I believe that you have install WDAG and turn on related setting under Windows Feature. You also mentioned enabling Application Guard with GPO.
Check both the Hyper-V and Windows Defender Application Guard box.
Windows Defender Application Guard requires Hyper-V to also be turned on.
Meanwhile. you could try to check if we could find and modify the settings below:
In the Windows 10 Search box type- Windows Security.
Select App & browser control.
Select the “Change Application Guard Settings” link from the right-side panel.
Another setting is below:
Windows Settings>Privacy>App permission>Location>Allow apps to access your location>on
After restart, if the issue still insists, I suggest that we could check for update to install newer security update. It will update system OS build and system files. Including the latest Edge version to check.
Hope this helps and please help to accept as Answer if the response is useful.
WDAG 0x8007274c Extended Error 0x0000001
I am struggling with enabling Application Guard on Win10 20H2 via GPO after ensuring that all BIOS and Windows Feature requirements are enabled. I see the below error when just attempting to trigger WDAG from the Edge browser menu option.
From what I can tell the virtual container is not either being started or is accessible, has anyone seen this error code before?
Any advice or assistance would be greatly appreciated.
