[Python] WindowsDowndate tool error: AttributeError: type object 'PathEx' has no attribute...

I've been trying to use a python tool called WindowsDowndate from github (for educational purposes, I've been given the task to demonstrate some Windows exploit) but running the code just does not work.

Windows_downdate.py imports numerous methods from another file called filesystem_utils.py, where the error takes place:

from windows_downdate.filesystem_utils import PathEx, is_file_contents_equal, is_path_exists, read_file, write_file


The PathEx class is defined in filesystem_utils as follows:

import filecmp
import os
from typing import Union, List, Any, TypeVar, Type, Self
from pathlib import WindowsPath, _from_parts


class PathEx(WindowsPath):
"""
Extended WindowsPath class that supports NT path
"""

TPathEx = TypeVar("TPathEx")

def __new__(cls: Type[TPathEx], path: str, *args: Any, **kwargs: Any) -> TPathEx:
"""
Create a new instance of PathEx, expanding environment variables in the provided path

aram path: The initial path
aram args: Additional positional arguments
aram kwargs: Additional keyword arguments
:return: A new instance of PathEx
"""
expanded_path = os.path.expandvars(path)
args = (expanded_path, ) + args
self = cls._from_parts(args)
return self

@property
def nt_path(self: Self) -> str:
"""
:return: The NT path as string
"""
return f"\\??\\{self.full_path}"

@property
def full_path(self: Self) -> str:
"""
:return: The full path as string
"""
return str(self)


I am a very amateur programmer so please forgive my ignorance, I don't quite know how to handle someone else's code.
