Thanks for that.

I have this recipe in the .spec file, and the app finds the .txt files in the 
same location, so I don’t think it is this.

That’s a good lead, but it appears that .png doesn’t need a special plug-in for 
Qt, it is built in. As far as I can tell, the png library Qt uses is libpng and 
is included in /Qt5.11.0/5.11.0/Src/qtbase/src/3rdparty/libpng, but Pyinstaller 
doesn’t seem to import this part of the Qt installation, unless it bundles it 
into some other file or component of the app.
