Hey, found this issue in an earlier thread - here is the link to the thread:

https://github.com/pytube/pytube/issues/1199#issuecomment-1016783092

“” I just updated the regex like this and it’s working: ^\$*\w+\W “”

sorry had to edit - the image alone was not specific at all, note the change implemented on line 30 of cipher.py:

One slash was cuted in answer above. Correct: ^\$*\w+\W

This fix helped me. Thank you.
