I use the undo-tree package from GNU Elpa. Recently, the undo

(undo-tree-undo) stopped working when I edit .tex files with
AUCTeX (in
LaTeX-mode). As far as I can tell, it works as expected in all
other modes.
Emacs seems to hang and I have to hit C-g repeatedly to be able
to edit again.
The default M-x undo command still works.
I'm not seeing any problem, undo-tree works just fine in AUCTeX.
What versions of Emacs and AUCTeX are you using? What OS? I'm on
Linux, Emacs 26.3 and AUCTeX 12.2.0.
Since I have a lot of customizations, it's possible the cause is
somewhere in my
init file. But before I try to track it down, I wonder if
anyone else
experienced this problem and have some ideas.
Check out Emacs sandbox:
https://github.com/alphapapa/emacs-sandbox.sh
It allows you to run a clean Emacs instance without your
customisations. You can then install AUCTeX and undo-tree into
that instance (Melpa is pre-configured) and test if the problem
occurs. When you quit Emacs, everything is cleaned up. Your config
isn't touched at all, you can even start the Emacs sandbox safely
while your regular Emacs is running.
This way you can find out if your config has anything to do with
the issue you're seeing.
