Crash on start

Crash on start:
It looks like the dependencies install fine, but just a moment after the "Humble Email:" prompt appears, the log messages show up and freeze up the entire command prompt. Can't get it to respond again once this crashes.

Update: I left the command window alone while I wrote up this ticket, and soon after I finished the command window had updated with "Terminate batch job?"
So apparently the batch file is still alive in there, but the window goes unresponsive until something times out.
I've tried every Win/Nix key combination I know trying to get it to break while it's frozen, but nothing seems to work other than waiting or closing the window.
