Crash when song is changing

[PoSayDone]

I've changed some code in utils.py and in spotify_lyrics.py because I dont want to get metadata and lyrcis. I need only artwork. Maybe I broke something
Here is the changes:
utils.py

def fetch_lyrics(artist, title):
    final_lyrics = ('')
    return final_lyrics

spotify_lyrics.py

    def print_metadata(self):
        self.changed = True
        os.system('clear')
        utils.move_cursor(0, 0)
        print()
        print()
        print()

 album_cover = canvas.create_placement(
            'album_cover',
            x=4, y=9,
            width=28,
            height=28,
            )
        album_cover.path = self.image_file
        album_cover.visibility = ueberzug.Visibility.VISIBLE
