Can you please try the latest pre-release and let know if the issue still happens?

I gave it a try using the latest pre-release and it works as expected.

Code

        selected_files.value = (
            ", ".join(map(lambda f: f.name, files)) if files else "Cancelled!"
        )

    async def handle_get_directory_path(e: ft.Event[ft.Button]):
        directory_path.value = await ft.FilePicker().get_directory_path()

    page.add(
