GUI Scientific Calculator not running , using Tkinter

I'm trying to build a GUI Scientific Calculator using Tkinter, but my code does not want to run. Whenever I run it it says "Additional Information may be available in output window" and this: <The program 'python.exe' has exited with code -1 (0xffffffff)> pops up, there are no other errors evident when I run it , so I can't seem to figure out what the issue is. Any help would be of great assistance. Thanks in advance :)

from tkinter import *
import math as m


window=Tk()
window.title("Nitas' Scientific Calculator")
window.geometry('350x450')
window.configure(bg='purple')
