NET10 - Exception on quit

[GiorgioITS]

Description

Android application created with NET MAUI 10 (latest release - Long Term Support)
Tested in Emulator API 36
With the MainPage on screen, clicking the Back button passes though an unhandled exception before closing the app.

Steps to Reproduce

1. Create an application NET MAUI 10.0
2. Capture lifecycle events
3. Start Android emulator, API 36
4. Run the application
5. Click the Back button
   Expected result: the application quits
   Actual result: Unhandled exception ‘Android.Runtime.JavaProxyThrowable’ showing for a few seconds, then the app quits

I'm getting the following exception when on app startup for Android. It used to work fine in 9.0.120.

Current Version: 10.0.10
