App crashes in iOS13+ while navigating from Tabbed Pages inside Master Details to Login Page

I am setting the Main Page as Login and then set the Home Page as Main Page, Home Page is Master Details page and in that Details page is the Home Tabbed Page which is the Tabbed page and whatever the navigation I am doing is on the tabbed page current page. In Logout I am trying to navigate to Login page.
I used -
Application.Current.MainPage = new NavigationPage(new LoginPage());
Also tried -
Navigation.InsertPageBefore(new LoginPage(), this);
await Navigation.PopToRootPageAsync();
But it's getting crash only in iOS 13+ and working fine in below 13 iOS OS version.
Please help me....
I would suggest you look at the XCode Console when your app crashes
After you connect your iPad to your Mac via dock cable, you can start XCode and go to Window -> Devices and Simulators.
The window that pops up allows you to open the device logs and start the Console application. The Console application will list debugging information that are being streamed from the device in real-time. This is very handy when you want to trigger some feature and observe a resulting error.

how to enable message box in IIS server

I am building web application using vb.net 2008.
when I debug using the common complier it can show the Message box, but when I use IIS server the message box can't be shown and cause error page.
the error page says:
Showing a modal dialog box or form when the application is not running
in UserInteractive mode is not a valid operation. Specify the
ServiceNotification or DefaultDesktopOnly style to display a
notification from a service application.
is there any setting need to be done to solve this case?
Thanks,
Use could specify the ServiceNotification or DefaultDesktopOnly style, as the error message already told you:
MessageBoxOptions Enumeration
ServiceNotification
The message box is displayed on the active desktop.
The caller is a service notifying the user of an event. The function displays a message box on the current active desktop, even if there is no user logged on to the computer.
DefaultDesktopOnly
The message box is displayed on the active desktop.
This constant is the same as ServiceNotification except that the system displays the message box only on the default desktop of the interactive window station
DefaultDesktopOnly will cause the application that raised the MessageBox to lose focus. The MessageBox that is displayed will not use visual styles. For more information, see Rendering Controls with Visual Styles.
But ask yourself: When you rund a web application, how is going to sit before the server, ready to read and click the MessageBox? Maybe to want to write such messages to the event- or application log instead.

Default login popup for web sites

I am trying to build a web site with ASP.NET MVC, I'm new to this. My question is: how can I display the default login dialog? I am not referring to a custom dialog, like the jQuery Dialog, there is a default pop-up for credentials, which looks different depending on browser, same as with javascript alert(), but I don't know how to display it. To know what I mean, go to http://fit.c2.com/wiki.cgi?WelcomeVisitors, there is a Login button at the bottom of the page, when you click it a pop-up appears. That is what I want to display. Any ideas?
So there is no way I can do this with FormsAuthentication?
That dialog is the result of a challenge-response authentication initiated by the server.
In the context of IIS, you would get this if you used windows authentication with no anonymous access.
You do not display this dialog or have anything to do with it other than restricting access to the resource in question.
