What is this "invalid command name while executing error" in tkinter, why does it happen, how do I fix it in my code?

Question

I am a student who is learning python. I am currently making an alarm in tkinter GUI. When I run my code I see this error: ""invalid command name "2268780354496_check_events" while executing "2268780354496_check_events" ("after" script)""

My code:

from tkinter import *
import tkinter
import time
import winsound

clock = time.ctime(time.time())
clock = clock.split()[3]
hour = int(list(clock)[0] + list(clock)[1])
mint = int(list(clock)[3] + list(clock)[4])
sec = int(list(clock)[6] + list(clock)[7])

root = Tk()

root.title("Alarm")
root.iconbitmap(r"E:\Python\Nishu Code\Clock GUI\Clock.ico")
root.configure(background="#2c2c2c")
root.geometry("300x280")
root.resizable(False, False)

hour_label = Label(root, text = hour, bg = "#2c2c2c", fg = "White", font = ("Times", 15, "bold"))
hour_label.place(relx = 0.2, rely = 0.5, anchor = CENTER)

mint_label = Label(root, text = mint, bg = "#2c2c2c", fg = "White", font = ("Times", 15, "bold"))
mint_label.place(relx = 0.5, rely = 0.5, anchor = CENTER)

sec_label = Label(root, text = sec, bg = "#2c2c2c", fg = "White", font = ("Times", 15, "bold"))
sec_label.place(relx = 0.8, rely = 0.5, anchor = CENTER)

    global hour
    if hour != 23:hour+=1

    return hour

    if hour != 0:hour-=1
    else:hour=23

    return hour

    return sec

    global sec
    if sec != 0:sec-=1

    sec_label.config(text=sec)
    return sec

        time.sleep(1)
        if alarm_time == current_time:
            winsound.PlaySound("Alarm01.wav",winsound.SND_ASYNC)


heading = Label(root, text="Alarm", bg="#2c2c2c", fg="white", font = ("",20,""))

mainloop()

and this is the error

The error keeps coming as long as the code is running Any doubts about the code please tell me and PLEASE solve my problem. I am doing my coding in Spyder
