Thank you, I appreciate the answers to my question. I agree it was very vague in nature and appreciate the resources given. For those who navigate here with a similar vague problem, here is the solution we found.
We set up a virtual box and built our code to test what was happening. It turned out that it was version 17 of node.js that was causing our problem. Version 16.x worked perfectly.
Though not satisfactory, this was the cause of our build hanging. Of course, we have a lot of further investigation to do to understand why this version is giving us trouble.
