uninstall it and again install ffmpeg and pydub I also got the issue solved like that

The relevant error output is the "Only 8000Hz sample rate supported" part. This is because amr files can only store 8000Hz audio, but your song file is at a different sample rate. This can be solved by converting your sample to 8000Hz before exporting as follows: song.set_frame_rate(8000).export(out_f="haha.amr",format="amr")
