Why am I getting this error?

[EvanzGuti10]

I am new to the world of flet, I was trying to learn with the available documentation, as well as the examples that are included, but when I started I ran into this problem:

Exception in thread Thread-1 (__connection_loop):
Traceback (most recent call last):
File "C:\Users\Wolf\AppData\Local\Programs\Python\Python312\Lib\threading.py", line 1073, in _bootstrap_inner

How can I solve it, it doesn't let me run any examples, thanks in advance

Can you please share the code that you are trying to run so we can see what is going on?

import flet as ft

def main(page: ft.Page):
page.title = "Flet counter example"
page.vertical_alignment = ft.MainAxisAlignment.CENTER

txt_number = ft.TextField(value="0", text_align=ft.TextAlign.RIGHT, width=100)

def minus_click(e):
    txt_number.value = str(int(txt_number.value) - 1)
    page.update()

def plus_click(e):
    txt_number.value = str(int(txt_number.value) + 1)
    page.update()

page.add(
    ft.Row(
        [
            ft.IconButton(ft.icons.REMOVE, on_click=minus_click),
            txt_number,
            ft.IconButton(ft.icons.ADD, on_click=plus_click),
        ],
        alignment=ft.MainAxisAlignment.CENTER,
    )
)

ft.app(target=main)

I tried your code and had no issue.
If you are still facing this error, can you provide more details? (full error traceback, python version, flet version...)
