Hello Uduak,
Thank you for posting your question and sorry to hear that you have ran into troubles running the plugin.
Perhaps the first thing you can try is to run the plugin in QGIS 3.10? The newer versions of QGIS have some aspects changed and the plugin has not been tested for these versions of the QGIS. If you are following the Open University version of the course you can follow the QGIS installation instructions here:
https://docs.google.com/document/d/15_MOZG-olhjNTONax4sXuszXIEgVgnz0 to download QGIS 3.10.
Another thing that I notice from your error message is that you seem to have spaces and dashes in your paths. Please remove these (or replace them with underscores), some tools can run into troubles if you have spaces in the path names.
In conclusion try this:
1. Install and run on QGIS 3.10 following the instructions in the link above
2. Remove the dashes and spaces in path names
Hopefully this should fix your issues. Please let me know how it goes.
Best, Babak
