    It's working correctly for me in 1809 (17763.55) but I can confirm that in 1803 (17134.376) F12 Developers Tools behaves exactly as you describe. This is now acknowledged by Microsoft as a Known Issue.

    Microsoft said:
    Developer Tools (F12) may fail to start in Microsoft Edge.
    Cumulative Update KB4462933 Windows 10 v1803 Build 17134.376 - Oct. 24 - Windows 10 Forums

    MS do provide a workaround in the above KB article, but as today is Patch Tuesday I would wait to see if this will fixed in the next cumulative update, due out at 10:00am PST (Redmond, Washington) or about six and a half hours from now.

    As a workaround until then for a page you want to look at with F12, in Edge click the 'three dots' menu and select 'Open with Internet Explorer'. I can confirm that Developers Tools are working normally in IE for 1803 17134.376.

    @gabgab, I can confirm that Edge's F12 now works properly in 1803 with the latest cumulative update to build 17134.407.
