getting going with Xlwings 0.30.15 on Excel 2019

Question

I've installed Xlwings 0.30.15 into Excel 2019 and then went to its ribbon and entered the path (L:\refinitiv\python\mb.py) to the UDF Modules and the Interpreter. Data entered was tripled checked as correct.

When I click "import functions" I get a popup cmd window and an Excel window, both containing errors and when I try to use any function from the python field I get a "#NAME" error in excel.

I also have a Refinitiv Excel add-in installed and functioning correctly. This is a COM add-in. I have checked with Refinitiv and there does not appear to be a compatibility issue as they publish articles like "How to integrate Financial Data from Refinitiv Data Platform to Excel with Xlwings" (which didn't address my issue).

The content of the CMD prompt window is:

xlwings server running, clsid={4CCCB3D7-7D80-4154-A661-62E0EC20FA00}, event loop on 23316
pythoncom error: Python error invoking COM method.
