More information was requested, but none was given within 4 months, so
I'm closing this bug.

I get this trace:

--8<---------------cut here---------------start------------->8---
  tramp-file-name-handler(file-readable-p "/scp:remote:/path/Contents/Resources/site-lisp/cal-move.so")
  calendar-cursor-to-visible-date((8 24 2021))
  calendar-generate-window(8 2021)
  calendar-basic-setup(nil)
  calendar()
  run-hooks(midnight-hook)
  apply(run-hooks midnight-hook)
  timer-event-handler([t 24869 56416 388128 86400 run-hooks (midnight-hook) nil 0])
--8<---------------cut here---------------end--------------->8---

I do have a file "/scp:remote:/path/foo/bar/baz.py" open.
"remote" is not accessible because the VPN is down.
"/scp:remote:/path/" is the location of the .git directory for baz.py.
"remote" is linux, localhost is mac. of course there is no
Contents/Resources/site-lisp/cal-move.so on "remote".
How come "calendar" calls "tramp"?
when I click on the function name in *Backtrace* to get to the source
code, tramp is called and I get an infinite loop of
"Tramp: Opening connection nil for remote using scp...failed"
I have to C-g and M-x tramp-cleanup-all-connections to get back to editing.
