Solution exception error UTCIMap module failing to generate UTCI plot


I am trying to run the UTCIMap module within grasshopper and at the final calculation step, I get an error as below:

I have the epw file pulled in and some CFD wind speeds integrated to calculate the UTCI plot.
I am using a mesh resolution of 2m to capture some local effects in terms of UTCI.
I am using a Windows machine with Rhino 7.0 for reference.
Any insights would be helpful.
