Description

Video links with a list argument will always download the whole playlist, even with --no-playlist specified either in a config file or on the command line. I believe this was introduced in version 2020.11.12.

I can confirm that this issue happens for me too.

I can confirm too, option noplaylist does not make sense. To prevent such behaviour I use code listed below to clean up url from list parameter.

from urllib.parse import parse_qsl, urlencode, urlparse

url = urlparse(yt_url)
    if url.query.strip():
        query_params = parse_qsl(url.query)
        # Drop 'list' parameter from youtube url query string due to 'noplaylist' option does not make sense.
        query_params = [(f, v) for (f, v) in query_params if f != 'list']
        new_query_string = urlencode(query_params)
        yt_url = yt_url.replace(url.query, new_query_string)
