SettingsExpander or SettingsCard crashes the application when NativeAOT enabled

[Baka632]

Describe the bug

When I enable NativeAOT by the following code in my project file:

<PublishAot>True</PublishAot>

And defined a SettingsExpander (or a SettingsCard) in a really simple way:

<Grid>
    <controls:SettingsExpander Header="Hello!" HeaderIcon="Accept" />
    <!--<controls:SettingsCard Header="Hello!" HeaderIcon="Accept" />-->
</Grid>

It crashes on startup, getting an exception: Microsoft.UI.Xaml.Markup.XamlParseException:“XAML parsing failed.”

Steps to reproduce

1. Enable NativeAOT in project file, using `<PublishAot>True</PublishAot>`.
2. Add a `SettingsExpander` or `SettingsCard` to the layout.  
3. Run the application.  
4. Observe that the application crashes.

Expected behavior

The application should not crash when NativeAOT enabled.

@Baka632 can you please let us know what version of the WASDK and Toolkit you are trying to use this on?

I am unable to reproduce this issue on my machine using AOT in debug and release mode, with/without debugger attached:

You need to be using the latest preview for AOT support of the Toolkit - 8.2.241112-preview1.

    <PackageReference Include="CommunityToolkit.WinUI.Controls.SettingsControls" Version="8.2.241112-preview1" />
    <PackageReference Include="Microsoft.Windows.SDK.BuildTools" Version="10.0.26100.1742" />
    <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.6.241114003" />

I am using the latest stable version of Toolkit: 8.1.240916 (and WASDK 1.6.241114003).
After updating to latest preview version of Toolkit, I solved this problem, thanks to your reply!
