Some news about the investigation. The org-mode version of the emacs -Q is Org mode version 9.1.9 (release_9.1.9-65-g5e4542 @ /usr/local/share/emacs/26.3/lisp/org/). It's pretty old but the latex compilation works fine.
When I change to Org mode version 9.3.7 (9.3.7-24-g7b657c-elpa @ /home/djj/.controlled-emacs.d/elpa/org-20200831/) The same issue arises. tabular* instead of tabular. I don't know how to change the version of org-mode without restarting. But with my .emacs brought to minimun and I just uncommenting the following command. (add-to-list 'load-path "/home/djj/.controlled-emacs.d/elpa/org-20200831") (require 'org) is enough to generate the issue.
