Describe the bug

I created an flet project according to the documentation Create a new Flet app, then typed the command directly in the terminal flet build windows, but encountered an error. I'm using Windows 11.

Code sample

Code

# main.py
import flet as ft


def main(page: ft.Page):
    page.window.title_bar_hidden = True
    page.window.title_bar_buttons_hidden = True
    # page.padding = 0

    page.add(
        ft.Row(
            [
                ft.WindowDragArea(
                    ft.Container(
                        ft.Text(
                            "Drag this area to move, maximize and restore application window."
                        ),
                        bgcolor=ft.Colors.AMBER_300,
                        padding=10,
                    ),
                    expand=True,
                ),
                ft.IconButton(ft.Icons.CLOSE, on_click=lambda _: page.window.close()),
            ],
            # spacing=0,
