kivy on replit: Unable to find any valuable window provider

This is my code:
`

import kivy
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput


class RegScreen(GridLayout):

  def __init__(self, **var_args):
    self.cols = 2
    self.add_widget(Label(text='First name'))
    self.firstname = TextInput(multiline=True)

    self.add_widget(self.firstname)
    self.add_widget(Label(text='password'))
    self.password = TextInput(password=True, multiline=False)

    self.add_widget(Label(text='Confirm password'))
    self.password = TextInput(password=True, multiline=False)
    self.add_widget(self.password)

    class Load(RegScreen):

      def build(self):
        return RegScreen()

    if __name__ == '__main__':
      Load().run()

And this is the error:

[CRITICAL] [Window      ] Unable to find any valuable Window provider. Please enable debug logging (e.g. add -d if running from the command line, or change the log level in the config) and re-run your app to identify potential causes
sdl2 - ImportError: libXext.so.6: cannot open shared object file: No such file or directory

I tried installing certain dependencies that I had found in other solutions, hoping it would solve the problem but it didn’t and repilt’s shell showed this:
