Strange Problem with Shell FlyOut on Android

[enny1170]

Hello all, i have developed a small Maui app witch is working on Ios and Maccatalyst. But when i try to start them in a Android Emulator the app crashes after display the main page. I have try'd different Emulators and Versions.
The Debugger shows me that the cause of the crash setting style on the ShelFlyout. This not happen's on Ios and Maccatalyst.

To find a Workaround i have created a new App from Template and use only the Style created for my App. By deactivating my Styling step by step, i discovered the fallowing Styling as cause of the Problem.
<!-- this style causes the problem on Android <Style TargetType="Label" Class="FlyoutItemLabelStyle"> <Setter Property="TextColor" Value="{AppThemeBinding Light={StaticResource Secondary}, Dark={StaticResource SecondaryDarkText}}" /> <Setter Property="FontAttributes" Value="Bold" /> <Setter Property="FontSize" Value="20" /> <Setter Property="FontFamily" Value="OpenSansSemibold" /> <Setter Property="HeightRequest" Value="100" /> </Style> -->
Without them, the app works as expected.
The Question is, how i can style my FlyoutItem in a way that not run into the crash ?

Many thanks for any suggestion.
