Ok, so i verified whether the example works even on dev-main, so it's not a broken dependency, Also it looks that PHP is able to resolve the example namespace which is only available via composer's "require --dev" command. So another guess would be a missing autoloader include.
Also it would be less guessing if you could include a code example of yours that produces that output.
