(end-of-defun) not working as expected with auctex.
reddit / emacs

The command end-of-defun which is bound to C-M-End or C-M-e with
auctex would usually take me to the end of the current environment. I
updated emacs recently and it no longer works as expected. It takes me
to the end of the document instead of the current environment. Is this
a known bug or am I missing something?

The counterpart of this command (beginning-of-defun) works as
expected.

Do you have the latex-extra package installed?

I don't have latex-extra package. I installed it but I am failing to
enable the latex-extra-mode because it can't find tex.buf.

That's good. I asked because latex-extra redefines some navigation
commands like C-M-f.

I'm seeing the same problem here. The affected environment for me is
`alignment`. I just updated to `Emacs 28.1` so I guess it is a bug.
Have you ever fixed it?

I'm running Emacs 28.2 and the problem still persists. I haven't fixed
it but I found a work-around by remapping my keyboard shortcuts to
something that works.

I see. Thanks for the update.

I looked into `end-of-defun` and noticed that it calls `end-of-defun-
function` to determine the end of the defun. That said, the current
value is a compiled function that I'm too scared to rewrite. I guess
it might be relevant for adding self-defined environments.
