meld won't start on Cygwin: Complains about the dbus library

I'm trying to get meld to run on Cygwin 64 (just updated - September 2021), on Windows 10. Some relevant package versions: * meld: 3.18.0-1 * python3: 3.8.6-1 * python36: 3.6.13-2 * python2: 2.7.18-4 I'm also using MobaXTerm's X server (and it works - I can run xclock for example.) I've resolved this initial issue , by running meld using Python 3.6. Still, when I try to run meld, this happens:

$ meld
process 14421: D-Bus library appears to be incorrectly set up; 
failed to read machine uuid: Failed to open "/etc/machine-id": No such file or directory
See the manual page for dbus-uuidgen to correct this issue.
  D-Bus not compiled with backtrace support so unable to print a backtrace
Aborted (core dumped)

How is my d-bus library "incorrectly set up"? How to I correct its setup? And how do I get meld to finally run?
