Research direction
Start by reproducing the vertical PNG join on macOS using the Homebrew installation of ImageMagick 7.1.2-27, then inspect why the PNG decode delegate is unavailable despite libpng being installed. Done means identifying the installation or delegate problem and confirming that two PNG images can be joined vertically without the reported error.
