Runtime error while running the recommended basic usage command

After following the installation instructions and running python3 scanner.py <file_name>, the program raises an exception. The console output reads:

Traceback (most recent call last):
  File "...\Python\pythoncore-3.14-64\Lib\argparse.py", line 1748, in _check_help
    formatter._expand_help(action)

    return help_string % params
           ~~~~~~~~~~~~^~~~~~~~
ValueError: unsupported format character ')' (0x29) at index 113

The above exception was the direct cause of the following exception:
