You should raise any MAUI specific issues with that repository. ImageSharp and Fonts use standard .NET APIs.

you can find bug by those steps:

create template maui app (official template project), it include fonts file in 'Resources/Fonts/'
move a font file to root

run code

        var stream = FileSystem.OpenAppPackageFileAsync("OpenSans-Regular.ttf").Result;
        var collection = new FontCollection();
        var family = collection.Add(stream);

u will find an exception with message "maui special method not support"
platform：MAUI Android 13 Debug mode
it's a bug or due to my error operation? or just not support good to maui?

You need to understand. If MAUI has constraint you need to confirm them with the team responsible. None of the APIs used in this codebase are subject to platform restrictions. I.E it should run anywhere the >NET runtime is installable.
