Installed cygwin test to try to diagnose another issue - but not

Attempting to cygport upload - just hung without start ftp connection.
Reran cygport --debug upload and command hanging was ssh-add -l!
Confirmed by rerunning command ssh-add -l from bash.
Killed eventually with series of ctrl-C and ctrl-\.
Reran under strace and output log attached.
No version or help output from ssh-add so:
$ ssh -V
OpenSSH_9.7p1, OpenSSL 3.0.14 4 Jun 2024
After running setup and reinstalling 3.5.3, ssh-add -l works
normally, and cygport upload succeeds to ftp package.
Only variable was the cygwin version installed.
I have experienced otherwise inexplicable hangs of ssh that have
been resolved by killing ssh-agent and restarting it. This doesn't
happen very often, so it is usually mystifying when it does occur --
until I remember.
I have *NEVER* had *ANY* issues using (Open)ssh etc. for remote
login, shell, commands, file trees, or git (and earlier vcs) access,
professionally and personally, over many years, releases, and
systems, mainly from Cygwin/-X shells and sessions (due to using
mainly Windows desktops with various Unix servers), with/out
authorized_keys, passphrases, and/or keychain, until these recent
instances under the test build.
I'm not above suspecting my problems arise from something unique in my
setup, but it hasn't occurred often enough for me to investigate further.
It wasn't clear to me whether your problem was readily reproducible. You
repeated the ssh-add command, and it hung, but you didn't report having
killed ssh-agent. If it was actually ssh-agent that was hung, I would
absolutely expect ssh or ssh-add to hang trying to talk to it.
