I want to create a javafx app that displays youtube live streams but for some reseaon only live streams dont work with javafx

I am using the java JDK version 23 with javafx version 17.0.6. My controller looks like the following controller

public class HelloController {
    @FXML
    private WebView WebView;

    @FXML
    public void initialize() {
        System.out.println("Controller initialized");

        this.WebView.getEngine().load(";);
    }
}

This code works fine when using a non-livesstream youtube video: .

But when I change the YouTube id to a live stream it will display an error.

And when i right click in the Webview and copy the debug code i get this:

This looks like an error from youtube because i get no error in the console. Is there a work around so that i can still display youtube live streams or is this an bug with youtube?
