Usually, it's a crash and your app closes, and there is a Java stacktrace of the missing type.

It looks to me like the inner exception is lost: `The type initializer for 'Microsoft.Maui.Handlers.ButtonHandler' threw an exception.` It doesn't say what the exception was. Hard to know if this...

They don't have default wildcards for proguard files: https://github.com/dotnet/maui/blob/f6424476e57c1c25cc587f164b90bceb1681cd37/src/Controls/src/Build.Tasks/nuget/buildTransitive/netstandard2.0/Microsoft.Maui.Controls.Globs.props#L43-L55 So, you probably need `

Generally r8 has no idea if C# calls a Java method, so it will remove them otherwise. It doesn't think anyone called it from Java.

So, are you saying the `ICameraProvider` type is missing? Can you share what NuGet it is from and what namespace it's expected to be in? Thanks!

Did this problem start happening with the recent update: * https://www.nuget.org/packages/Xamarin.AndroidX.Camera.Extensions/1.4.2.2 Or is the problem also there for older versions?
