Aseprite infinite loading bug

The current Unity version is version 6000.0029, and the image is downloaded aseprite file and used. However, when I press play the game,

The improting(iteration) window that says image/player/weapon.aseprite is loading infinitely. Is there a solution? There was a simple case like this before, and I had to force quit it, but now when I press the game play button, the loading window keeps popping up.

Since I can’t speak English, I had a translator help me.

Hello there,
Please file a bug report so that we can take a closer look. Thanks!

How do I submit a bug report?? There was no other way for me to choose in that situation other than force quitting.

If it freezes when loading the project up, you could change the file ending of the aseprite file to e.g. .bug and report the issue from the bug reporter inside the editor.
