this works fine in Xamarin build, but gives above in MAUI build

This sounds like a problem external to RichTextKit where the ReadOnlySpan type isn't resolving correctly for some reason. Are you able to use ReadOnlySpan in other places in your project?

yea, upgrading skia and all related from 80.3 to latest preview 88.0-254 fixed the problem
