Hello, I think I have found the reason for the issue and I can reformulate the situation like this: "the presence of any column after #+LATEX_HEADER: breaks the export* if there is no blank space* between #+LATEX_HEADER:and the rest of the line." This only applies to* emacs running on MS-Windows* since the absence of space caused not problem with my previous emacs (GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.20, cairo version 1.16.0) with Org mode version 9.6 (9.6-??-e7ea951 @ /home/olivier/.emacs.d/.local/straight/build-27.2/org/). Conclusions - I should have better looked at section 17.8 of the manual to see that one space is always present after the column and the word - Maybe the first sentence of this section should be changed like this to stress on this detail: " In-buffer settings start with ‘#+’, followed by a keyword, a colon, *a blank space* and then a word for each setting."
