Answer 1

Try run command

find . -type f -name "*.png" | xargs -L 1 -I{} file  -I {} | grep -v 'image/png; charset=binary$'

in your root project directory, it will show you all files that have .png extension, but are not pngs. Then you can resave them as png in some image editor. Before running this command clean project, to speed up the process.
