Problem on start

Hi!

I have a small problem when starting an application from the IDE. When I press F9, the code is compiled (Delphi 12) and the browser opens. But there is just an empty page (the title on top tab is corect) and the loading never ends (the rortating sign in the top tab is always displayed).

I open the dev console and see the "Debugger paused" text in the "Sources" tab

But the console is empty, no errors, nothing.

I then pres F5 or click "Resume script" in the Sources tab, then the page is normally loaded.

I tried to change the order of the libraries in the index.html, but no results, I'm not even sure that there is the source of the problem.

Here's the index.html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <meta content="width=device-width, initial-scale=1" name="viewport"/>
    <meta $(ThemeColor)/>
    <noscript>Your browser does not support JavaScript!</noscript>
    <link href="data:;base64,=" rel="icon"/>
    <meta $(Manifest)/>
    <link $(FavIcon)/>

    <script src="$(ProjectName).js" type="text/javascript"></script> 

    <style></style>
  </head>
  <body>
<meta $(BodyParameters)/>
  </body>
  <script type="text/javascript">rtl.run();</script>
</html>

Strange, I have not seen this before. Could there be any browser plugin that interferes?

Uh, I didn't tought about this - i will disable all plugins and recheck. Stay tuned.. :)
