Android Release : MainPage = new NavigationPage(new ContentPage()); crashes

[nk54]

Description

https://learn.microsoft.com/en-us/dotnet/maui/user-interface/pages/navigationpage

The code given crashes in Release mode on Android (no problem on Debug. I didn't test iOS).
Works on Windows (Debug & Release too).

public App()
{
    InitializeComponent();

    ContentPage startPage = new ContentPage() { Content = new Label() { Text = "Hello" } };

    // App Crashes
    // MainPage = new NavigationPage(startPage);

    // App starts
    MainPage = startPage;
}

I think it worked in RC1

Steps to Reproduce

Just try to set MainPage as a NavigationPage
(AppShell is too far from being ready to be used : relative navigation not supported, those kind of stuff)

Link to public reproduction project repository

https://github.com/nk54/maui_bug_navigation

Version with bug

7.0 Release Candidate 2

Last version that worked well

7.0 Release Candidate 1

Affected platforms

Android

Affected platform versions

Android 9 and up

Did you find any workaround?

Deploy my debug app of 60 MB instead of 30 MB....... (once optimized otherwise 160 MB)

Relevant log output

This must be a P1 because it is very trivial and I never saw a Xamarin/MAUI app without navigation.

It is mandatory. It is a regression.

I'm a XAML guy since Silverlight and I can wait.

But a developper without experience of Xamarin/MAUI will uninstall everything if the basic Navigation from the documentation, one of the first thing he will try crashes.

Might be related to dotnet/maui#5168 and dotnet/maui#4311

But the issue was fixed and closed. I think it's another regression

Hmm running this I'm seeing the following exception in release mode

@jonathanpeppers thoughts?

@nk54 if you put <AndroidLinkResources>false</AndroidLinkResources> in your project file does the problem go away for you?

Thank you for suggestion! This works for my issue dotnet/maui#11069

Issue solved adding

AndroidLinkResources false /AndroidLinkResources

in file csproj.

[PriyaGnana]

I too face the same issue, but it does not resolve on adding AndroidLinkResources as False to me.
I tried adding it inside the PropertyGroup of android release configurations.
Any suggestions?

@PriyaGnana
U need to identify the issue of your crash..

1. Connect device via USB cable
2. run "adb usb" from C:\Program Files (x86)\Android\android-sdk\platform-tools
3. run "adb logcat > C:\logcat.txt"
4. Launch app on device an make it crash.
5. open the file logcat.txt. and u'll see the cause of crash.

in my casy the crash error was
