RuntimeError: input(): lost sys.stdin - Directly after an asciimatic's animation

I was curious if anyone had any insight to this error I am having. I have a program in python that run's an intro-animation using asciimatics. Following this animation, I attempt to get input from the user using input(), but get the following error -> RuntimeError: input(): lost sys.stdin. I know asciimatics has to take some control so sys.stdin/sys.stdout, and perhaps this is the root of the problem.

Animation

def demo(screen):
    scenes = []
    scenes.append(PlasmaScene(screen))
    screen.play(scenes, stop_on_resize=True, repeat=False)

def main():
    Screen.wrapper(demo)

Where it's called

clear()
animate_intro() # asciimatic animation
clear()

LOGGED, USER = login_entry(None) # input() called in 'login_entry()'

Error Thrown

RuntimeError: input(): lost sys.stdin

As discussed... This appears to be some complex interaction between asciimatics use of win32 and the cmd command prompt on windows.

It wasn't reproducible on my system, but using subprocess.run("python games/life.py") instead of os.system appears to have fixed it.
