I am using Vanilla Emacs.
Note that Doom is known for carelessly advising some Org functions and
can sometimes break things. Such issues should be reported to Doom
developers.

There is no such Org version. Our latest version tag is 9.5.4.
If you are seeing 9.6-..., it indicates some problem with your package
manager. I suggest to purge your local downloaded Org copy and
re-install Org.

9.6 means that your Doom is not clean enough. There is some problem with
your Org source code used by Doom.

What do you mean by "breaks too many other things in org"?

I do not think that "/home/user/.emacs.d/modules/lang/org/lisp/autoload"
contains Org source. AFAIK, Doom using using straight.el, which puts the
packages sources into .emacs.d/straight/repos/ and
.emacs/straight/build/. Though Doom might use different paths.

You can try to watch the video I recorded on testing Org issues:
https://open.tube/videos/watch/4d819114-43bf-42df-af94-f94fc53dd0d9
There, I showcased how to get a clean Org setup + vanilla Emacs.

Again, there is no such tag. There is official release version, which is
9.5.4; and there are two development branches: bugfix and main. The
bugfix is WIP minor release branch for 9.5.5 and main is the development
branch for next major release. Note that Doom is using the development
(main) branch, AFAIK.
