Python + Kivy, the program window opens and immediately closes, gives an error?

Question

Python

The code itself:
from kivy.app import App
from kivy.config import Config
from kivy.uix.textinput import TextInput
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.anchorlayout import AnchorLayout
class MyApp( App):
def build(self):
al = AnchorLayout()
bl = BoxLayout(arientation='vertical', size_hint=[.4, .4])
bl.add_widget(TextInput())
bl.add_widget(Label(text= "Press ctrl + c to enter password"))
al.add_widget(bl)
return al
if __name__ == "__main__":
Config.set('graphics', 'fullscreen', 'auto')
Config.set('graphics', 'window_state', 'maximized')
Config.write()
MyApp().run()
Here is the error:
Traceback (most recent call last):

Process finished with exit code
strictly do not judge if it is stupid

Answer 1

bl = BoxLayout(arientation='vertical', size_hint=[.4, .4])
