Why isn't any Flet code running on my system?

Question

im trying to make an app with Python Flet and i thought it would be good to try a simple hello world program first, and so i did. As the tutorial said to pip install flet that worked. then i tried the code

import flet as ft

def main(page: ft.Page):
    page.add(ft.Text(value="Hello, world!"))

ft.app(target=main)

this error:

LSOpenURLsWithRole() failed with error -10825 for the file /Users/turtle/.flet/bin/flet-0.12.2/Flet.app.
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/threading.py", line 973, in _bootstrap_inner

Process finished with exit code 0

also im using pycharm CE on macOs (10.13.6 intel processor) if thats a problem
