I was able to reproduce using exact steps, using Emacs master.
Emacs 29.4 has no problem. Loading external Org mode repo also works.

Sounds like something about autoloads? I am not sure.

The problem is triggered by

(defcustom org-babel-latex-process-alist
  `(,(cons 'png (alist-get 'dvipng org-preview-latex-process-alist)))

in ob-latex.

`org-preview-latex-process-alist' is defined in org.el and the backtrace
in the reproducer points to org.el loading ob-latex. Somehow, only on
master, `org-preview-latex-process-alist' is not available.
