My first attempt at using GNU Radio Companion produced this error log:

I am running GRC on a Windows 10 Pro workstation.
I am using a Hack RF One from Great Scott Gadgets which has a label on the side "r4-p6" but does not identify this as a model/rev ID.
I ran the first example from Great Scott Gadgets Hack RF One Tutorials which is located here: https://greatscottgadgets.com/sdr/1/
This example combines the OSMOCOM Souce and WX GUI FFT Sink modules.
I have attached the grc file, the top_block.py and the GRC configuration file.
The error occurred when I clicked on the "Execute the Flow Graph" Icon.
I would appreciate any help getting past this error.
