Problem: MonoGame 3.8 integration into .NET Maui for Android platform

[arothe0815]

How can one integrate the famous MonoGame 3.8 C# rendering API with .NET Maui Apps on Android?

My (urgent) problem:
All my trials to initialize MonoGame 3.8.1105 from a Maui App (e.g. via a derived GLSurfaceView UI control), which uses OpenGL-ES as hardware backend for rendering, are failing to initialize MonoGame's top-level Game() class or a separated GraphicsDeviceService(Game) with a NullReferenceException of unknown origin/root-cause from within the MonoGame library!

Question:
Are there any suggestions or experiences on how to integrate MonoGame more successfully into .NET-Maui on Android, ideally a small code example, if existent. What could be the potential technological limitation causing the GraphicsDeviceService initialization to fail, given that the OpenGL-ES initialization appears to work, hence marking intact availability of the GPU hardware to the App itself?

Many thanks for your considerations and help in advance and in any case! Andreas
