[FIXED] Python: Tkinter TclError: can't invoke "image" command

Issue

preface: I have currently tried most things and there are few qusestions asked on stackoverflow on this question and i cant seem to wrap my head around it so im going to need some help

application: the purpose of this program is to animate an oval and a picture, the oval works fine, but the picture is struggling, you could remove the image or alien2 and the program should run fine.

CODE

image form

from tkinter import *
import time
from PIL import Image,ImageFilter
from PIL import ImageTk

class alien(object):
     def __init__(self):


        self.root = Tk()
        self.canvas = Canvas(self.root, width=400, height = 400)
        self.canvas.pack()
        self.cardPath = Image.open('bubble.png')
        self.resCard = cardPath.resize((100,100))
        self.CardVar = ImageTk.PhotoImage(resCard,master=root)
        self.alien1 = self.canvas.create_oval(20, 260, 120, 360, outline='white',fill='blue')
        self.alien2 = self.canvas.create_image(100,100,CardVar,anchor=CENTER)
        self.canvas.pack()
        self.root.after(0, self.animation)
        self.root.mainloop()


     def animation(self):
        track = 0
        while True:
            x = 5
            y = 0
            if track == 0:
               for i in range(0,51):
                    time.sleep(0.025)
                    self.canvas.move(self.alien1, x, y)
                    self.canvas.move(self.alien2, x, y)
                    self.canvas.update()
               track = 1
               print("check")

            else:
               for i in range(0,51):
                    time.sleep(0.025)
                    self.canvas.move(self.alien1, -x, y)
                    self.canvas.move(self.alien2, -x, y)
                    self.canvas.update()
               track = 0
            print(track)

alien()

TclError: can't invoke "image" command: application has been destroyed

I know the code is not beautiful, but it's a test environment and as mentioned everything should work flawless, but it breaks when an image is used instead of an oval which should not make a big difference. Thanks in advance!

PROBLEM SOLVED

turns out the problem turned up when assigning master inside PhotoImage(), when i removed that the application did not get the TclError

NEW PROBLEM

the changes i made to the code were from this:

        self.cardPath = Image.open('bubble.png')
        self.resCard = cardPath.resize((100,100))
        self.CardVar = ImageTk.PhotoImage(resCard,master=root)

to this:

    self.cardPath = Image.open('bubble.png')
    self.resCard = cardPath.resize((100,100))
    self.CardVar = ImageTk.PhotoImage(resCard)

Solution

After a while i edited the code and made it work. here is the full code

from tkinter import *
import time
import PIL
from PIL import Image,ImageFilter
from PIL import ImageTk

class alien(object):
    def __init__(self):

    self.root = Tk()
    self.canvas = Canvas(self.root, width=400, height = 400)
    self.canvas.pack()

    CardVar = ImageTk.PhotoImage(file='bubble.png')
    self.alien1 = self.canvas.create_oval(20, 260, 120, 360, outline='white',fill='blue')
    self.alien2 = self.canvas.create_image((100,100),image=CardVar,anchor=CENTER)
    self.canvas.pack()
    self.root.after(0, self.animation)
    self.root.mainloop()


 def animation(self):
    track = 0
    while True:
        x = 5
        y = 0
        if track == 0:
           for i in range(0,51):
                time.sleep(0.025)
                self.canvas.move(self.alien1, x, y)
                self.canvas.move(self.alien2, x, y)
                self.canvas.update()
           track = 1
           print("check")

        else:
           for i in range(0,51):
                time.sleep(0.025)
                self.canvas.move(self.alien1, -x, y)
                self.canvas.move(self.alien2, -x, y)
                self.canvas.update()
           track = 0
        print(track)
alien()

The problem

the cardVar was never able to find the correct image even though it was in the same folder, so i tried to do cardVar.show() and another image that was located far away showed up so it seems like something was saved in my memory. so i decided to restart kernel and everything went smooth
