Creating image button EEZ studio issue with LVGL 9.x LVGLimage.py

I had project working with non-image buttons. Then I changed buttons to image by adding
an Image source in Background field of the button (I assume this is the correct way make an image button?)

After creating image buttons I get build error for EEZ Studio LVGL9.x,

So I tried to install Python 3 with pypng and lz4 modules. lz4 module requires MS visual
C++, which I did install. Rebooted system But I still can get the Lz4 module to install.

Any help would be appreciated!
