from kivy.app import Appfrom kivy.uix.button import Buttonclass TestApp(App): def build(self): return Button(text="Hello,kivy")TestApp().run()

Output Result:

Then I queried the relevant documentation on GitHub:

https://github.com/kivy/kivy/issues/3889
Download the KIVY.DEPS.SDL2:
C:\users\usth1>pip Install KIVY.DEPS.SDL2

Output Result:
