Pytube Error while trying to download a YouTube video

I'm trying to download a youtube video using python. However, i'm getting thrown an error even though my code is right according to many up-to-date videos.

I am using Python 3.9.9 and Pytube 15.0.0

Here is my code:

from pytube import YouTube

video = YouTube('https://www.youtube.com/watch?v=AWXvSBHB210')
video.streams.get_highest_resolution().download()`

Full error:

Traceback (most recent call last):
  File "C:\Users\Tobias\AppData\Roaming\Python\Python39\site-packages\pytube\__main__.py", line 181, in fmt_streams
    extract.apply_signature(stream_manifest, self.vid_info, self.js)

    name = re.escape(get_throttling_function_name(js))

    raise RegexMatchError(
pytube.exceptions.RegexMatchError: get_throttling_function_name: could not find match for multiple

During handling of the above exception, another exception occurred:

    video.streams.get_highest_resolution().download()

    raise RegexMatchError(
pytube.exceptions.RegexMatchError: get_throttling_function_name: could not find match for multiple

This is the error I get specifically: get_throttling_function_name: could not find match for multiple

I just got the same error today. The solutions is here: https://github.com/pytube/pytube/issues/1954

You have to find and open the file ../site-packages/pytube/cipher.py and add one more pattern into the function_patterns list:

r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])\([a-z]\)',

So my final list (at the line 264) look like this:

function_patterns = [
    # https://github.com/ytdl-org/youtube-dl/issues/29326#issuecomment-865985377
    # https://github.com/yt-dlp/yt-dlp/commit/48416bc4a8f1d5ff07d5977659cb8ece7640dcd8
    # var Bpa = [iha];
    # ...
    # a.C && (b = a.get("n")) && (b = Bpa[0](b), a.set("n", b),
    # Bpa.length || iha("")) }};
    # In the above case, `iha` is the relevant function name
    r'a\.[a-zA-Z]\s*&&\s*\([a-z]\s*=\s*a\.get\("n"\)\)\s*&&\s*'
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])?\([a-z]\)',
    r'\([a-z]\s*=\s*([a-zA-Z0-9$]+)(\[\d+\])\([a-z]\)',
]

Python 3.11, pytube 15.0.0, macOS Monterey 12.2
