Crash after navigating from one page (with navbar) to another one without navbar

[nevse]

Description

Project to reproduce https://github.com/nevse/Maui12NavigationwithNavBar. Just click on "Goto page2!" button and application will crush.

I created two pages. One page wrapped in NavigationPage and another is not. And I simply navigate from one page to another on button click

private void OnCounterClicked(object sender, EventArgs e) {
    Application.Current.MainPage = new MainPage2();
}
