"Kivy 2.0.0，python 3.9 错误：[CRITICAL] [Window] 无法找到任何有价值的 Window 提供程序"

Question

I've been having this same error running any kivy code I type into IntelliJ. I'm using kivy 2.0.0 and Python 3.9. Here's my code:

import kivy
kivy.require("2.0.0")
from kivy.app import App
from kivy.uix.button import Button

print(kivy.__version__)

class ButtonApp(App):
    def build(self):
        # use a (r, g, b, a) tuple
        btn = Button(text="Push Me !",
                     font_size="20sp",
                     background_color=(1, 1, 1, 1),
                     color=(1, 1, 1, 1),
                     size=(32, 32),
                     size_hint=(.2, .2),
                     pos=(300, 250))

        btn.bind(on_press=self.callback)
        return btn

    def callback(self, event):
        print("button pressed")
        print('Yoooo !!!!!!!!!!!')

root = ButtonApp()

root.run()

I've tried many solutions including: reinstalling kivy, adding to path, and I've installed all the dependencies. Here's the error message:

EDIT So thanks to weebify I got through, I posted the full method I used as an answer.

The solution for this problem is to uninstall kivy and reinstall the cutting-edge version from master:
