You have this error because the exit() function calls itself recursively. Replace it with

def exit():
    root.destroy()

I changed it and it works, Thank you. but now i'm having the problem of when i hit star the loop starts running and i cant shut it down because the exit button doesn't respond. how can i multi thread a button ?

A good principle is to avoid time.sleep() with GUIs because it freezes the GUI. You can use tkinter's after() method. Something like

startClickingVar = False

def click_forever():
    if startClickingVar:
        mouse.click(Button.left, 1)
        root.after(1000, click_forever)

def startClick():
    global startClickingVar
    if not startClickingVar:
        startClickingVar = True
        click_forever()

def stopClick():
    global startClickingVar
    startClickingVar = False
