In your comment you say this:
I have a close-and-kill-next-pane function defined in my .init. I use that to kill windows that I just needed temporarily, help docs, etc.
After I identify the issue, I want to close the debugger and work on my code. By habit, I hit the keybinding for close-and-kill-next-pane and instead of the debugger going away, what ...

So the sequencing is a bit tricky as mentioned in the comment below, but reselecting the previous window seems like the easiest way:
(defun my-debug-hook ()
;; Selecting the window in `debug-mode-hook' is too early, it will
;; confuse the debugger's code, causing it to replace the current
;; buffer contents with the backtrace, and reset `buffer-undo-...

along with a message about the desktop file already being in use
Emacsclient does not attempt to process the desktop file, so you are clearly starting a new instance of Emacs.
If emacsclient can't connect to the server, but you either passed it -a '' or --alternate-editor='' or else have the ALTERNATE_EDITOR environment variable set to an empty string, ...

You can force entering the debugger when a function is called,
(debug-on-entry 'myf)
Any calls to myf triggers the debugger. A (myf 2 3) call, for example, would result in
Debugger entered--entering a function:
* (myf 2 3)
...
Remove it when you're done,
(cancel-debug-on-entry 'list)

It looks like you can call it like this:
(let ((calendar-latitude 40.1)
(calendar-longitude -88.2)
(calendar-location-name "Urbana, IL"))
(sunrise-sunset))
This does not prompt you for the latitude and longitude, and puts a message in the minibuffer for those variable values.

Two things were actually missing:
- libxml2 dependency
- proper setting of nov-unzip-program
I could add libxml2 the easy way by going to Emacs FTP, download the dependencies, and apply them in my Emacs installation directory.
For the set of nov-unzip-program I had to download Unzip for Windows, and set the path in init.el:
(setq nov-unzip-program "C:\\My\\...

The function sunrise-sunset is an interactive function takes a numeric prefix argument as a parameter. It does not take the latitude and longitude as parameters, which is what you're trying to pass into it. I suggest reading this emacs wiki article as well as of course the manual itself to learn more about prefix arguments. Also checking out the interactive ...

I just found out what's wrong. Elisp requires a backslash in a string (i.e., between double-quotes "") to be escaped in Lisp, so the following code works:
(setq org-latex-classes
'(("article"
"
\\documentclass[12pt,a4paper]{article}
\\usepackage{xeCJK}
%\\usepackage[heading]{CJK}
\\usepackage{zhnumber} % package for Chinese formatting of ...

In Lisp, the term/word that follows an open parenthesis (if the open parenthesis is not quoted) is interpreted to be a function, not a variable. In the context of this question, to is a variable. Because the word to follows an open parenthesis that is not quoted, Emacs thinks it was meant to be interpreted as a function instead of a variable. Try instead ...

As an answer I cite here the page M-: (info "(elisp)Eval List") of
emacs-version: GNU Emacs 26.2 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.22.30) of 2019-04-12 (the feature is actually rather old)
You can use the “evaluation list buffer”, called ‘edebug’, to evaluate
expressions interactively. You can also set up the “evaluation list” of

Partially it is already there in
GNU Emacs 26.2 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.22.30) of 2019-04-12.
If you save a file test.el with the following contents, instrument f for edebug, step into f, and call ilem you can access the local variables x, y, and i in the ielm repl.
(defun f (x)
(let ((y (+ x 1)))
(cl-loop for i from 0 below ...
