[BUG]AttributeError: 'NoneType' object has no attribute 'span'

Before creating an issue I am on the latest version of pytube 11.0.2 my pip is at the latest version

Describe the bug So i can not download any videos using stream() method, I faced this issue yesterday as well and found a solution to change something in the cipher.py line 293, i did that and it worked for the rest of the day fine, when i woke up and tried to test it again the same error occurred even tho the line was changed and it is still changed as it was

To Reproduce Please provide the following information:

• ‘http://www.youtube.com/watch?v=UUGtYLqtaxc’

•           print(url)
            yt = YouTube(url)
  
            video = yt.streams.filter(only_audio=True).first()
  
            print(SAVE_PATH)
            out_file = video.download(SAVE_PATH)```
  
  
  

Expected behavior Well it should download the video!

Output

This is a duplicate of #1225. The temporary fix is to change the name from ’ name = “iha” ’ to ’ name = “jha” ’

Well “jha” no longer works lol, it worked at first and everything going smoothly but yeah, it’s temporary fix after all
