self.tk.call(('image', 'create', imgtype, name,) + options) _tkinter.TclError: couldn't recognize data in image file "image1.png" - Unable to load png

Question

I'm trying to make an app using Python and Tkinter but I'm not able to load an image, or png to be specific. Instead, I'm getting this long error:

 File "C:\Users\username\AppData\Local\Programs\Python\Python310\lib\tkinter\__init__.py", line 4038, in __init__
    self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't recognize data in image file "image1.png".

Can someone help me fix this? Here are the lines of code that might be causing the error:

cycle1IMG = tk.PhotoImage(file="image1.png")

def openNewWindow1():
    newWindow = Toplevel(master)
    newWindow.title("🚲Cycle 1")
    newWindow.geometry("750x500")
    Label(newWindow, text="Cycle 1", image= cycle1IMG).pack()

cycle1 =tk.Button(
    root,
    text="🚲Cycle 1",
    command=openNewWindow1
    
)
cycle1.place(x=500,y=300)
