Weird error

[BoiGeezums]

No idea what I'm doing re: coding whatsoever, just downloaded python like 20 mins ago to try your tool and I'm getting this error when I try to run the replay option:
C:\Windows\System32>yttool --replay https://youtu.be/QmwdHxjoUiI
Traceback (most recent call last):

obj, end = self.scan_once(s, idx)

I also tested with a different video, resulting in a different error while getting some of the comments:

It works fine when using the example link you used, but when I used videos I wanted to get the replay for, it didn't.
