just to clarify a bit, we are using 84.0.522.40, and have been since we started rolling out (about 4 weeks now), this issue did not exist until today. We have also not applied ANY updates except Windows defender updates (which are set to automatically approve).

  I've just had a coworker show me that error. It also started after the installation of Edge 84.0.552.40.
  OS is Windows 10 Enterprise 1909 UBR 900 (June updates).
  
  So far I only know about 1 affected installation/user and I cannot reproduce the issue on any of my test systems. Really weird.
  
  I've opened a case with Microsoft about it. Let's hope this gets fixed fast before it spreads.

    I have a solution:
    
    Check if this value exist: "https://getadmx.com/?Category=Windows_10_2016&Policy=Microsoft.Policies.InternetExplorer::URLFailsPol" in:
    Registry Hive : HKLM or HKCU
    Registry Path : Software\Policies\Microsoft\Internet Explorer\Main or Software\Microsoft\Internet Explorer\Main
    
    And delete this

  Running IEMode sites in standalone fixes this issue, but I would rather not open another IE Window to fix this issue.
