NavigationView's navigation will throw an unhandled exception in some situations, causing the UI thread to throw a fast fail and freeze

Describe the bug

The output will like these below:

I'm not sure which part caused this issue, but I had already carefully checked my code by making the settings page a blank NavigationView frame page, and it can still be encountered.
You'll meet this each time when you navigate to settings page if you enable VS's Debugging>xaml hot reload function.

But you'll hardly meet if you turn off it but still can encounter it if you are not in VS or is released mode.

Why is this important?

Navigation will fail and the app crashed.

Steps to reproduce the bug

I think the issue is hard to reproduce in a blank project. So you can directly use my app under development.

Actual behavior

No response

Expected behavior

No response

Screenshots

Check all break when throw it's like

But it's hard to reprduce by start in windows' app list.
The window froze here:

NuGet package version

2.4

[zhuxb711]

I also met this issue. Don't know how to work around it😂
Same stacktrace as yours

[zhuxb711]

Scott Jones (@Scottj1s) Could you please help take a look? Thanks~

[zhuxb711]

I'm able to reproduce this issue in a demo project

Please check: CrashNavigationView.zip

[zhuxb711]

hoshiizumiya Could you also be able to reproduce this issue using the demo project?

[hoshiizumiya]

Ruofan (@zhuxb711) Of course, it's true.

[zhuxb711]

ayushjai19 Could you please help take a look or assign a colleague to check what is going on?

[hoshiizumiya]

I observe the same situation when close the window, the exception stack is in the ~NavigationView. Some reference count problem?

[zhuxb711]

ayushjai19 I have already provided a sample to reproduce this issue but seems no one care about it. All the release note that published recently in full of fix and add API for "AI", leaving thousands of issues in WinUI aside and ignore them. A few of WinUI issues being fixed is simply because it's the requirement of Windows Explorer team. They could open an internal ticket and ask your team fix it and we can not.
