Error when attempting to open png

When attempting to open a png I get the following error:

libpng: Not a PNG file
Error reading PNG file
Error loading frame 1 from file "D:\Pixelart (D)\Kingdom Hearts\BlackBall.png"

I am 100% certain it is a png. What is going on here?

Hi @JoeReMi, would you mind to share the png file with us? You can send it to and we can take a look why it doesn’t work.
