Corrupt Image file when uploading to testflight

Hi, our app has been using single size app icon for a while and today when I trying to upload a new version of our app I got an email from App Store Connect saying

ITMS-90013: Corrupt Image File - The image file 'AppIcon60x60@2x.png' appears to be corrupt.

We haven't touched the image for ages and these 60x60 image were generated by Xcode from the single 1024x1024 image supplied. I've tried to use a new image and still got the same error.

Does anyone experienced this recently?

Same and same. It actually worked earlier in the day, i guess a bug on Apple's side?
