Back button is not visible for a page in MAUI

[IXChinmayD]

I am working on the Migration of Forms Application to .NET MAUI .NET 8 with Prism version 9.0.401-pre. In Xamarin forms,

I can see the navigation bar with the back button for some screens. But, in MAUI, the back button and title of the page are not visible.

I have attached screenshots for your reference

The navbar is visible on Android when I write the below code:-

CreateWindow("NavigationPage/MainPage", exception => Console.WriteLine(exception))

But it crashes on the iPhone with error: No root window has been created

The No root window has been created occurs because the navigation failed and thus no Window was created with a root page. If you look at the Navigation Exception it will give you hints as to what happened. The problem lies in your code.
