'_tkinter.TclError: неверное имя команды ".!canvas"' во время вызова `move` ⇐ Python

[Anonymous]

Мой 9-летний сын изучает Python и столкнулся со следующей ошибкой в ​​своем коде (игра с пузырьками):

Код: Выделить всё

Traceback (most recent call last):
File "M:\Yandex disk\YandexDisk\ДЕТКИ\python modules\Bubble Blaster.py", line 64, in 
move_bubbles()
File "M:\Yandex disk\YandexDisk\ДЕТКИ\python modules\Bubble Blaster.py", line 55, in
move_bubbles
c.move(bub_id[i], -bub_speed[i], 0)
File "C:\Users\User\AppData\Local\Programs\Python\Python310\lib\tkinter\__init__.py", line
2949, in move
self.tk.call((self._w, 'move') + args)
_tkinter.TclError: invalid command name ".!canvas"*

Я дважды перепроверил весь код, но не нашел ошибок.
Вот весь код:

Код: Выделить всё

from tkinter import *

ship_id2 = c.create_oval(0, 0, 30, 30, outline='red')
SHIP_R = 15
MID_X = WIDTH / 2
MID_Y = HEIGHT / 2
c.move(ship_id, MID_X, MID_Y)
c.move(ship_id2, MID_X, MID_Y)

Что вызывает эту ошибку?
