ImportError when calling pdfgui from WSL terminal

[maak-sdu]

Followed the guidelines at https://www.diffpy.org/products/pdfgui.html to install pdfgui within its own conda env in a WSL (Windows Subsystem for Linux) terminal. Trying to run pdfgui, the following error is encountered (the whole installation process is attached as a .txt file):
