I had a similar problem on linux.
This line tells you where the problem is:

File "/opt/homebrew/lib/python3.9/site-packages/chessli/tactics.py", line 41, in read_lichess_puzzle_database
puzzle_df = pd.read_csv(url, names=column_names, compression="bz2")

Apparently lichess database file is not as pandas expects (last line says: pandas.errors.ParserError: Error tokenizing data. C error: Expected 10 fields in line 3, saw 11), because in some lines it has more columns.
In order to tell pandas to only read 9 columns even if more are present i added in line 41 of this file "/opt/homebrew/lib/python3.9/site-packages/chessli/tactics.py" the following command:

usecols=range(0, len(column_names)),

So line 41 should be something like:

puzzle_df = pd.read_csv(url, names=column_names, usecols=range(0, len(column_names)), compression="bz2")

(sorry for my english)
