I keep getting this error when I try to activate the app.py file:

Traceback (most recent call last):
File "app.py", line 2, in <module>
from flask import Flask, request
File "D:\--WORK--\ALFRED\Alfred_ENV\lib\site-packages\flask\__init__.py", line 21, in <module>
from .app import Flask, Request, Response
File "D:\--WORK--\ALFRED\Alfred_ENV\lib\site-packages\flask\app.py", line 782
def run(self, host: object = None, port: object = None, debug: object = None, options: object) -> object:
^
SyntaxError: non-default argument follows default argument
