Am I the only one who experience that 9 of 10 times Blazor hangs with this message when I use authentication, and after I have logged in?
Any hints on how to get past this issue?
The screenshot looks like Chrome debugging with multiple tabs open. Have you tried following the instruction on the screen?
Secondly, it is not clear what authentication you are using. I have a Blazor Identity demo app and I cannot reproduce the reported behavior.

Hi @Anonymous , I had a test in my side with blazor wsam + Azure AD, the default login mode is popup so that when I visit a page which having [Authorize] attribute, the browser would pop up a window and the main window would show us a tip with Checking login state..
Your issue might due to you enabled console window in Browser so that the debugger code in js makes the app pausing. Since we are lacking of information(authentcation scheme, related codes/changes/configurations), we are not able to reproduce your issue right now.

I have the same problem and I found out that it only happens when there is a breakpoint anywhere in my code. When there is no breakpoint, it never happens.
It even happens in swagger when I authenticate, so there is a good chance it has nothing to do with my code.

I don't have any breakpoint. Not only no breakpoint in my js code, but neither in my c# code. And still hanging. Not always, but still too often.

the issue is that the azure login page (which is running in a different tab via the popup option) is throwing javascript errors, which the debugger catches. the popup option has know issues and does not work in all senerios. as suggested by the browser, go to the tab and click debug continue
