Publishing Error- Files cannot be found

Hoping someone can please help. When I try to publish my experience it says that files cannot be found, but they are all png files l that I think would be associated with the drawing function and I’m not recognizing them as files that I would have added. Any suggestions or ideas for how to correct this issue?
Examples files names that are missing: “Clear-all-icon-IntuiFace-White.png, Selected-large-brush-icon-InutiFace-White.png, Volume-level-2-icon-IntuiFace-White.png, etc.” there’s a whole list of about 30 png files that show missing.

You are right these images are from the drawing tool icons.

Could you please create a thread with our support team so they can investigate your issue?
