Flet black screen

[FranciscoLucas1]

Question

I am experiencing a display error in the framework. When I enter the name and click the button to go to the next page, where there should be a message "Hello username" as programmed in the code, the page refreshes and displays a black screen. I asked a colleague to test the code, and everything seems to work fine for them, but for me, only the black screen appears

I'm using Windows 10, Flet 0,12.0 and Python 3.12

Code sample

import flet as ft

def main(page: ft.Page):

    def login(e):
        if not in_name.value:
            in_name.error_text = "Please insert your name"
            page.update()
        else:
            page.clean()
            page.add(ft.Text(f"Hello {in_name.value}"))
            page.update()


    
    in_name = ft.TextField(label = "Insert a name")
    button = ft.ElevatedButton("Entrar", on_click = login)


    page.add(in_name, button)

ft.app(target = main)

That's strange.
It works on my end as expected.
