pyttsx3 closing some GUI interfaces prematurely

[a2435191]

When I run pyttsx3 with, say, rumps or tkinter and use runAndWait, the GUI quits prematurely. Any idea why this might be happening/how to fix? I am running the following sample code on MacOS 10.14, Python 3.8.x.

import tkinter as tk
import pyttsx3

engine = pyttsx3.init()

def play_my_sound():
    engine.say("Hello world")
    engine.runAndWait()

window = tk.Tk()
window.after(1000, play_my_sound)
window.mainloop()

Try running play sound in a seperate thread.
