Android application crashes without debugger

### Description

https://github.com/janseris/MauiShellWrapperCrashOnStartupWithoutDebugger

### Steps to Reproduce

Run with debugger. OK
Run without debugger: crash on startup

This is a minimal sample from a larger app where instead of crash, plain black or plain white screen was shown in the application depending on current dark/light mode.

### Link to public reproduction project repository

https://github.com/janseris/MauiShellWrapperCrashOnStartupWithoutDebugger

### Version with bug

9.0.50 SR5

### Is this a regression from previous behavior?

Not sure, did not test other versions

### Last version that worked well

Unknown/Other

### Affected platforms

Android

### Affected platform versions

### Did you find any workaround?

No

Why does it work with debugger?

Run the linked MauiShellWrapperCrashOnStartupWithoutDebugger sample on Android with and without a debugger, starting from AppShellWrapper.xaml.cs and App.xaml.cs. Trace the XAML startup path through XamlLoader.cs, ApplyPropertiesVisitor.cs, and Page.cs, using the reported exception to compare both configurations. Done means the sample starts without a debugger on the affected Android versions.
