Pygame not working on Pycharm - "unrecognized selector sent to instance"

Question

I'm really struggling to get even basic code to run in Pycharm with Pygame. It's coming up with a load of errors and I've searched and searched and nothing has worked so far. I'm on a mac laptop. Below is the code I'm trying to run:

import pygame
pygame.init()

screen = pygame.display.set_mode([500, 500])

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

screen.fill((255, 255, 255))

pygame.draw.circle(screen, (0, 0, 255), (250, 250), 75)

pygame.display.flip()

pygame.quit()

And here is the error response I am getting:

[CAMetalLayer setDisplaySyncEnabled:]: unrecognized selector sent to instance 0x7fa6d971e5f0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CAMetalLayer setDisplaySyncEnabled:]: unrecognized selector sent to instance 0x7fa6d971e5f0'

I am running the latest Pygame, python and pip.

Looks like a bug in the Mac-specific portion of the Pygame library? The code (mostly) runs fine on Windows. — Carcigenicate, Jan 07 '21 at 20:18
I have installed pygame on my windows pc instead and it is working, thank you so much. Such a shame that it does not work on mac. — Olivia Berry, Jan 07 '21 at 20:40
Welcome SO Olivia! Have you checked out https://stackoverflow.com/questions/28003827/python-and-pygame-error-code-134-cannot-figure-out-why ? — demokritos, Jan 07 '21 at 20:41
The MacOS API they're using may have changed slightly, and Pygame has yet to update to reflect it? Potentially? It may be worth submitting an issue to the Github repo of the library. Also, try a reinstall just in case something went wonky with the original installation. — Carcigenicate, Jan 07 '21 at 20:42
It seems like it's attempting to make a method call `setDisplaySyncEnabled`, but from some searching, it looks like that's supposed to be [displaySyncEnabled](https://developer.apple.com/documentation/quartzcore/cametallayer/2887087-displaysyncenabled). And actually, there is a [github issue raised](https://github.com/pygame/pygame/issues/1970) for this exact problem already. It looks like you MacOS might be outdated? — Carcigenicate, Jan 07 '21 at 20:47
