PyGame screen not filling and flipping

This is the class of my game:

class App:
    def __init__(self):
        self._running = True
        self._display_surf = None
        self.clock = pygame.time.Clock()
        self.size = self.weight, self.height = 500, 640
        self.i = 0
    def on_init(self):
        pygame.init()
        self._display_surf = pygame.display.set_mode(self.size, pygame.HWSURFACE | pygame.DOUBLEBUF)
        self._running = True
 
    def on_event(self, event):
        if event.type == pygame.QUIT:
            self._running = False
    def on_loop(self):
        print(self.i)
        self.i += 1
    # here it should paint the screen green and then update the display
    def on_render(self):
        self._display_surf.fill(pygame.Color('green'))
        pygame.display.flip()
    
    def on_cleanup(self):
        pygame.quit()
 
    def on_execute(self):
        if self.on_init() == False:
            self._running = False
 
        while self._running:
            for event in pygame.event.get():
                self.on_event(event)
            self.on_loop()
            self.on_render()
            self.clock.tick(60)
        self.on_cleanup()
 
if __name__ == "__main__" :
    theApp = App()
    theApp.on_execute()

It should open a window with a green background, but instead it opens a window without background, just the default color of a window on MacOs with the dark theme.

Here's the window enter image description here

I tried using multiple colors to exclude the fact it was painting the wrong color, I tried calling update instead of flip, nothing works. Looking on other question of SO, they all say to do what I've already done by calling fill and then flip.

You are (probably) using the version of pygame that currently ships when installing it with pip3 install pygame.

From pygame's documentation :

Mac installation

Recent versions of Mac OS X require pygame 2.

I had the same problem and running pip3 uninstall pygame and pip3 install pygame==2.0.0.dev6 fixed it.
