Importing PNGs no work

I am trying to import a PNG that I made in pixelorama. I export the art as a PNG and make a sprite with the PNG.

What should happen

The sprite should load into the game and show up.

What is the actual result

Instead, a large X appears in place of the sprite, and when I load the preview, it is a pink squares.

Any Ideas?

Thanks.

What is size of that png?

It is roughly 64x64 pixels

Are there any other frames in the animation? If there are, delete those so only the most recent one is in the animation frames list.

it could be ur wifi if ur using website
