Steps to reproduce

Since Issue #15458103 is marked as 'fixed’. But it is not fixed at all I open a new issue…

For me the problem started after the last windows 10 update to1803. Before this update edge was not working at all (the known bug: opens and closes immediately).
Using windows 10 pro

Microsoft Edge 42.17134.1.0
Microsoft EdgeHTML 17.17134

Blank window when opening dev tool (F12), same as original post.
recently installed latest cumulative update (kb4284848) and all other windows 10 update available but that did not made any impact.

IE11 on the same system does not have this problem.

  • As per the original post, I experience the same issues with the F12 developer tools. Essentially, after enabling the F12 developer tools, the “inspect element” option becomes available within the right-click context menu, but utilising it (or the F12 keyboard shortcut) splits the window vertically, but the right-side window is blank/empty.

    I have repaired and reset the application through the “apps and features” interface, and have forcefully purged and reinstalled it via the PowerShell, but the issue persists. Version numbers are identical to the original post: Windows 10 Pro 1803 17134.137, Edge 42.17134.1.0, and EdgeHTML 17.17134. A virtual machine with the following version numbers does not experience the issue: Windows 10 Pro 1709 16299.522, Edge 41.16299.522.0, and EdgeHTML 16.16299).

    Anyway, this is the final straw for me with Microsoft Edge. In addition to the lack of functional developer tools, the real-world performance (i.e. not cherry-picked synthetic benchmarks) is atrocious.

  • Same here:
    Windows 10 Pro 1803 (Build 17134.165)
    Edge 42.17134.1.0
    EdgeHTML 17.17134

  • Hello all,

    Is everyone still experiencing this issue?  As mentioned in the previous ticket, I am guessing that creating a new user/account on the same machine does not have this issue?

    This issue was fixed, however, it appears that one some machines and for some upgrade paths that this issue persists.

    Some options:

    1. Use a new user account
    2. Run the “Reset this PC” and select to keep your personal files.
    3. Try running the health and DISM commands from the following link.  I am guessing that the powershell "reset edge"/appx remove and reinstall might be similar.

    Wish I had better an easier solution.  I would like to know if a recent update has corrected this issue for anyone.

  • For me it is not possible to create a new user account since i’m a user using server 2012 with active directories where user data (home dir/profile etc) are located.

    Since the tool can be run outside the browser window, is there a way (cmd line etc) to launch it separately and try if that works?

  • Reset, repair and reinstalling Edge did not help.

    Creating a new user is not an option. Tested with my personal account and also local Administrator account (which had not used Edge before).

    Resetting PC is also not possible.

    What is causing this issue?

  • Same here,
    Did a Dism which found no issues, then removed the edge dir in /user/…/packages/
    Rebooted machine reinstalled edge via powershell command etc.

    Still an empty development panel.

  • I also forced the Allow Developer Tool in the group policy for the local machine and on the Remote group policy for the clients on the server. regretfully this also did not made any difference.

  • This is occurring across the computers of the organization I work for. We are many web developers who need access to the development panel. It wouldn’t be realistic for everyone in the organization to reset their computers or use new profiles.

  • I have this issue and I can no longer do my work with your browser.

    I have a brand new, fresh, unmodified install of Windows 10 with Edge and no extensions. I work for a company with a fairly serious data policy.

    Microsoft Edge 42.17134.1.0
    Microsoft EdgeHTML 17.17134

    When will this issue be resolved?

  • If you are allowed to use powershell, execute the following command as your user to fix the dev tool:
    Add-AppxPackage -register “C:\windows\SystemApps\Microsoft.MicrosoftEdgeDevToolsClient_8wekyb3d8bbwe\AppxManifest.xml” -DisableDevelopmentMode -Confirm:$false

  • I can confirm that the Powershell fix from Daniel N. worked immediately without any problems.

    Thank you Daniel.

  • Confirming that the Powershell fix works on my PC.

    Thanks Daniel.

  • Thanks Daniel, not all heroes wear capes.

  • Indeed, it worked for me as well. Thank you.

  • What is the powershell command? Can I just say what we’re all thinking right now? Microsoft please stop with the web browsers. It’s quite clear you do not have the time or correct people to write a proper one. For years you have disappointed users and developers alike. At what point does one just give in and let others do it? There’s really no point in creating one. Is there?
