Hmm, so that's Org 9.3.  There aren't many plain assert's left in the
Org repo, just a few spots in contrib/ files (which aren't included in
Emacs):

  $ git grep '(assert\b' release_9.3
  release_9.3:contrib/lisp/org-attach-embedded-images.el:   (assert data)
  release_9.3:contrib/lisp/org-learn.el:  (assert (> n 0))
  release_9.3:contrib/lisp/org-learn.el:  (assert (and (>= quality 0) (<= quality 5)))
  release_9.3:contrib/lisp/ox-freemind.el:    (assert (symbolp (car parsed-xml))))

  $ git grep '(cl-assert\b' release_9.3 | wc
       37     191    3163

So...

...it does seem likely that the issue is outside of Org proper.  But
unfortunately I don't have any suggestions about where that might be, or
why it's getting triggered in the above scenario.  Hopefully others
will.
