lock keys and release keys based on a button press using PySimpleGUI and pyhook

I have created a program where the user get access to the system keys such as ctrl and alt only with exiting a program with a button press. However when i run the program it does get stuck in the UI and wont allow me to do anything. Where am i wrong in this? Thanks in advance.

import PySimpleGUI as sg  import pyWinhook  import pythoncom    layout=[[sg.Button('Exit')]]            def blockKeys(event):      if event.Key.lower() in ['lwin', 'tab', 'lmenu']:          return False    # block these keys      else:          # return True to pass the event to other handlers          return True    def releaseKeys(event):      return True            window = sg.Window('Window Title', layout, no_titlebar=True, location=(0,0), size=(800,600), keep_on_top=True).Finalize()  window.Maximize()  hm = pyWinhook.HookManager()  hm.MouseAll = releaseKeys  hm.KeyAll = blockKeys  hm.HookMouse()  hm.HookKeyboard()  pythoncom.PumpMessages()    while True:      event,values = window.read()      print(event,values)            if event =='Exit':          hm = pyWinhook.HookManager()          hm.MouseAll = releaseKeys          hm.KeyAll = releaseKeys          hm.HookMouse()          hm.HookKeyboard()          pythoncom.PumpMessages()          break;    window.close()
