It seems you're running AUCTeX as major-mode and not the builtin one.
Which version of AUCTeX are you using and how did you install it?

At any rate, I can't reproduce what you describe with this small file:

--8<---cut here---start->8---
\documentclass{article}

\begin{document}

Foo \cite{bar} bar.! Point here hitting M-q

\end{document}

%%% Local Variables:
%%% mode: LaTeX
%%% TeX-master: t
%%% End:
--8<---cut here---end--->8---

Can you come up with a recipe to reproduce with:

• Start Emacs with 'emacs -Q'
• Activate AUCTeX by eval'ing this in scratch (presuming you've
  installed AUCTeX from ELPA):
(progn
  (setq debug-on-error t)
  (package-initialize t)
  (package-activate 'auctex))
• In the file above (or any other example), tell us exactly where to put
  the cursor before hitting 'M-q'
• Show what the debugger says in your case.

You're welcome.  The above essentially says that AUCTeX isn't the
culprit per se since it works with the standard setup.

Thanks for the debug info, I have no idea why this happens in your
setup, so you have to dig further.  Some general ideas are:

• With your setup and your .tex file opened, do 'M-x
  list-load-path-shadows RET' and see if you have a stale AUCTeX
  installation on your HD; maybe you search also your HD yourself
• With your setup, load your .tex file, instrument[1] the function
  `LaTeX-indent-level-count' and trigger the issue.  Watch the function
  running[2] and where it chokes, maybe that helps
• Bisect your packages you load with AUCTeX and see which one breaks
  with your .tex file
• Just be on the safe side, uninstall AUCTeX via package manager
  interface, restart Emacs, and install AUCTeX again via the package
  manager interface.

HTH.  Best, Arash

Thanks for reporting back.  Maybe you want to report the issue to
latex-extra tracker[1].

I'm closing this report here since it's not an AUCTeX bug.

FWIW, this is what I see on macOS with NS-port:

And this is on Windows:

Both with "emacs -Q" incl. the value of `emacs-repository-version'.

I trapped into this as well, have a look at bug#72787.
