As suggested in the linked Geany issue, and the Stack Overflow
questions it referenced:

I added a firewall rule for the Geany.exe, restarted and tested (as
admin), without success.
I modified the firewall rule to add private networks, restarted and
tested (as admin), without success.

I turned off the Hyper-V feature, restarted, and tested (as admin, and
as user), with success.

Here success means that the "Failed to bind IPC socket" warning is gone.

I have not explored the consequences of turning off the Hyper-V
feature, especially with respect to Docker, Oracle VirtualBox, WSL,
WSL 2, etc.

Thanks for the help,
Doug
