Hey, replying to you here since it's a duplicate issue.
https://pastebin.com/0M2kf8D6 Here is the script I wrote that fixed the issue on my end, and what I did to the file before publishing. If you run this script on the same file, does the issue still persist? If so, I need to dig deeper as to why me running this code didn't fix it for everyone else, and if not... well I guess it's back to the drawing board. Sorry for the trouble! It seems that a few other assets have been effected by this type of error, too... If all else fails, it's just a bad .png file that can be deleted and everything else will work fine.
