Error: Painter not active
This is the result where I built and ran on Ubuntu 18.04 (using VirtualBox on Windows 10, because I haven't had successful build directly on Windows):

How can I solve this problem? Much appreciated!
Same Issue here

I am facing the same issue when doing texture defragmentation of my models. Can someone help with this issue????

I think you have to load a mesh with existing texture for this to work.
