The --max-quality option expects one parameter (the id of the maximum quality to download). It is not a way to make youtube-dl download the best quality available (which it does by default). In fact, --max-quality is used to select a worse video quality (for example, due to bandwidth restrictions).

Removing --max-bandwidth from your arguments should be sufficient to solve your problem.
