[Beginner Help] My space stuck on Starting with TypeError: argument of type 'bool' is not iterable

You passed a wrong argument for api_name in

    submit_btn.click(
        fn=process_audio,
        inputs=[audio_in, mode_in],
        outputs=[status_out, files_out],
        api_name=False
    )

It should be passed a string value (see Gradio Docs).

(Separately, be aware that there’s an ongoing issue with Hugging Face spaces building updates, which is unrelated to your code.)
