PyInstaller .exe keeps restarting itself

Question

I made something in python to test my python skills. I tried converting it to an .EXE (the main python file itself) but it keeps starting itself over and over again: https://youtu.be/GItuZkD8nfo it keeps starting new windows over & over again.

#define window height and width

#error text

quit_Image = PhotoImage(file = "quit.png")

#gui?
my_gui = MyFirstGUI(root)

#loop
root.mainloop() 

I tried adding

from multiprocessing import freeze_support
freeze_support()

but that did not work at all. I was expecting the program to work like normal.

Running the program from the normal .py file works just fine!
