Loops mess with mainloop. Use .after(). Your while loop will keep going on for ever because condition is always True.

def insert_(self):
      self.text_box.insert('end','hi\n')
      self.after(1000,self.insert_)

If you want to use while loop., use threading module.

from tkinter import *
from tkinter import ttk
import tkinter as tk
import time,threading
class __MENU__(tk.Tk):
    def insert_(self):
        while True:
            self.text_box.insert('end','hi\n')
            time.sleep(1)
    def insert_text(self):
        x=threading.Thread(target=self.insert_)
        x.daemon = True
        x.start()
    def __init__(self):
        tk.Tk.__init__(self)
        ....
        self.bnt=ttk.Button(self,text='start',command=self.insert_text).place(x=500,y=300)
       
if __name__=='__main__':
    __MENU__().mainloop()
