I hit the same bug when running emacs/master (5e940a353e37) and bisected it to:
commit 5a125fb5a9736bd3c67cf6ff9acc185d8e2260e2 Author: Kyle Meyer <k...@kyleam.com> Date: Sun Jun 9 13:06:28 2024 -0400 Update to Org 9.7.3 This is the org-mode commit that added (require 'ox-ascii) commit d38ca59230bd3b013398376c46719694948fe31e Author: Ihor Radchenko <yanta...@posteo.net> Date: Sat Jul 29 11:26:39 2023 +0300 ob-gnuplot: Fix links and verbatim when converting tables * lisp/ob-gnuplot.el (org-babel-gnuplot-table-to-data): Use custom backend to export table data. The backend will export links verbatim, without trying to resolve them and drop verbatim markers from data fields. Reported-by: Paul Stansell <paulstans...@gmail.com> Link: https://orgmode.org/list/camjkazzhulxpotg6fwugt-u8qshmub3kdqmk_e_0gh+juzm...@mail.gmail.com To reproduce the issue, run emacs -q then eval: (custom-set-variables '(org-babel-load-languages '((gnuplot . t) (emacs-lisp . t)))) and start org-mode.
