Application Guard closes the second it opens, any ideas for how I can fix this? RRS feed

  • Question

  • Greetings! For some reason, I'm having major issues with Application Guard.

    In "ordinary" Edge, Application Guard crashes about a second after it opens. Every time.

    In Edge Beta, the text everywhere is "blank".

    Here's a picture showing what I mean: https://i.imgur.com/9OhuGcm.png

    Any ideas?

    Windows 10 Pro N 1909, but this also happened in 1903.

  • Clear cache of Edge first and then recheck.

    • Open Microsoft Edge  and go to Settings and more > Settings  > Privacy & security.
    • Under Clear browsing data, select Choose what to clear.

    • Select the Cookies and saved website data check box and then select Clear.

  • Hi

    Did you happened to download any Add on within the Microsoft Edge? If you did, try to uninstall them and restart Windows, check if it works.

    Besides, Use the DISM tool and System File Checker for repairing any missing or corrupted system files:

    • Press CTRL+Shift+ESC to open Task Manager.
    • Click File > Run New Task
    • Make sure you have a check mark beside “Create this task with administrative privileges
    • Type CMD and hit Enter
    • If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
    • Type or copy paste the below command lines one by one into it and hit Enter key:

    DISM.exe /Online /Cleanup-image /Scanhealth

    DISM.exe /Online /Cleanup-image /Restorehealth

    sfc /scannow

    To close the Administrator: Command prompt window, type Exit, and then press Enter. Reboot your system to see if problem still occurs.

    If you are still not able to reinstall Windows Defender Application Guard after running the System File Checker, then follow the below steps to reinstall it from PowerShell

    • Click on the Start Menu > Search for PowerShell > Right-click on PowerShell > Click on Run As Administrator.
    • Once PowerShell is up and running, type the following command and hit Enter.
    • Disable-WindowsOptionalFeature -online -FeatureName Windows-Defender-ApplicationGuard
    • Once the above command is executed successfully, restart the computer once and again open PowerShell in Administrator Mode and type the following command in PowerShell and hit Enter.

    Enable-WindowsOptionalFeature -online -FeatureName Windows-Defender-ApplicationGuard

    • Alternatively, you can also go to Turn Windows features on or off and enable Windows Defender Application Guard from there as well.

    Once this command is executed successfully, restart the computer once and check if you are able to browse in the New Application Guard window.

    Hope can help you. Have a nice day!

    Best regards
