splat: [BUG] ReflectionTypeLoadException - Type '__callback_factory__class__' is not finished

Describe the bug I just installed the latest ReactiveUI (10.5.7) into my Xamarin.Forms (4.3) app, and built a single ViewModel out using it. I love it so far, and I did all of my testing using the iOS simulator.

Upon testing the app on my Pixel 4XL (Android 10), I immediately got the following runtime exception when I hit the new page/viewmodel.

PlatformBitmapLoader: Exception while detecting drawing types. - System.Reflection.ReflectionTypeLoadException: Exception of type 'System.Reflection.ReflectionTypeLoadException' was thrown.
Type '__callback_factory__class__' is not finished

System.TypeLoadException: Type '__callback_factory__class__' is not finished

followed by a really long list of this

PlatformBitmapLoader: DrawableList Type: Drawable PlatformBitmapLoader: DrawableList Type: Drawable PlatformBitmapLoader: DrawableList Type: Drawable PlatformBitmapLoader: DrawableList Type: Drawable PlatformBitmapLoader: DrawableList Type: Drawable

The end result is an extremely long delay in loading the page.

Steps To Reproduce Not sure how to fill this in. I’m assuming this is a tooling issue moresoe than anything else. I will give whatever information you ask for however.

Expected behavior Page should load instantaneously

notice in the gif where I press the (+) in the top right, there is an enormous delay and an enormous amount of output before the page loads.
