[Solved] This Image is Cursed

I'm getting this error after upgrading to Unity 2019.3.

Could not create asset from [Asset Path and Name]: File could not be read

The file looks like this in the editor (it has no thumbnail):

I tried to open the same png from a previous version of my game and replace that one but it's still not working. I even opened the previous version's file in Photoshop and saved a new image with a different name and it's still not working. I have a lot of graphics in my game that are suddenly not working or really messed up after upgrading, please help!

It's just a typical PNG sprite. The only settings I've changed is to change it from Default to Sprite in the editor. I'm not using any asset bundles or asset database or whatever, it's just a sprite!

Please help me with this I've tried to revert my game to a previous version but this issue happens every time I update to 2019.3.

 

PRAISE THE LORD I've found out how to exorcise this thing. It was breaking even if I opened the PNG and copied just the image with no layers or anything to a fresh file. It was breaking even if I imported it to a fresh Unity project. I was out of my mind. I was fearing for my life. I tried to upload the devil image here so I could see if any of you could figure out what the hell was up with it...then it told me I couldn't post it because it was too large. What? This tiny, barely 200x200 pixel image that should only be a few kilo - holy crap it's 15 MB HOW.

I still have no idea what the hell is in this image to make it that huge but I opened it back up in Photoshop and used PNG export instead of just Save As and made sure the exported file was only going to be like 7kb.

Now it works! It is pure again!

 

I'm running into a similar issue. I'm trying to copy an sample from my psd, paste it into an already existing png and pressing save, but this makes the filesize jump from 3kb to 12,780kb!!!! On top of that, Unity can't read the file. Doing the quick export option from photoshop works, but that requires several extra steps. I feel like Unity used to read pngs saved from photoshop this way and may photoshop changed something about the way they save pngs by default.

I wouldn't really call this problem solved since you need to do a tedious work around.

 

Had similar issue after upgrading project from unity 2019.2.21 to 2020.2.0.
Fixed issue by compressing image to lower size. Issue generated with the image size greater than 10mb.

Hope this might help someone to fix the issue.

 

Having the same issue in 2019.4.29f1 I found if I split the atlas in half on a frame boundary I could get it to load. I then stitch it back together internally.

Also found this is know bug they won't fix
