Python crash when using Tkinter and Pygame in one Script

Question

I have written a little Script that listens to MIDI events (sent by a DJ Mixer via usb) and sends UDP Packets to an IP adress (to switch Camera Angle). This works well, and i wanted to use it as a Standalone App in OSX. Since py2app does not show a console output, i tried to use a GUI instead. So i found an example of how to make a Tkinter GUI that outputs the Console text.

Both Programms work on their own, but when i try to do it all in one .py script, Python Crashes (with the OSX send report thing coming up).

Even when i run the scripts in Spyder, one after the other, it gives me random errors, and the Console needs to be restarted.

How can this be? i don't even have an error displayed...

import sys
from tkinter import Tk, Button, Frame
from tkinter.scrolledtext import ScrolledText

import os
import socket
import pygame as pg
import pygame.midi

class PrintLogger(object):  # create file like object

    def __init__(self, textbox):  # pass reference to text widget
        self.textbox = textbox  # keep ref

    def write(self, text):
        self.textbox.configure(state="normal")  # make field editable
        self.textbox.insert("end", text)  # write text to textbox
        self.textbox.see("end")  # scroll to end
        self.textbox.configure(state="disabled")  # make field readonly

    def flush(self):  # needed for file like object
        pass


class MainGUI(Tk):

    def __init__(self):
        Tk.__init__(self)
        self.title = "Camera Switcher"
        self.root = Frame(self)
        self.root.pack()
        # self.redirect_button = Button(self.root, text="Redirect console to widget", command=self.redirect_logging)
        # self.redirect_button.pack()
        # self.redirect_button = Button(self.root, text="Redirect console reset", command=self.reset_logging)
        # self.redirect_button.pack()
        self.test_button = Button(self.root, text="Test Print", command=self.test_print)
        self.test_button.pack()
        self.log_widget = ScrolledText(self.root, height=40, width=90, font=("consolas", "8", "normal"))
        self.log_widget.pack()
        
        logger = PrintLogger(self.log_widget)
        sys.stdout = logger
        sys.stderr = logger
        

        lastFaderUpCount = 0
        # input_main(0)


    def test_print(self):
        print("Am i working?")

def main():        

    lastFaderUpCount = 0
    input_main(0)


def input_main(device_id=None):
    global app
    pg.init()
    pg.fastevent.init()
    event_get = pg.fastevent.get
    event_post = pg.fastevent.post

    pygame.midi.init()




if __name__ == "__main__":
    app = MainGUI()
    app.title = "Camera Switcher"
    input_main(0)        

Sorry for the messy code... its copied together from many different sources...

Updated with a shorter version, the GUI stuff was all copied from here: How can I displaymy console output in TKinter?

The console output is:
