org-beamer-export-to-pdf generates \\\relax everywhere which makes latexmk complain

Hi,

This morning, I upgraded from Emacs 27 to Emacs 28 and to latest DoomEmacs.

Now, when I compile an org-Beamer presentation I had previously written & which compiled perfectly, latexmk outputs an error:


> ! Misplaced \noalign.
> \hline ->\noalign 
>                   {\ifnum 0=`}\fi \hrule \@height \arrayrulewidth \futurelet...
> l.519 \end{frame}

When I go the l.519 in the .tex file, I can see that now org-beamer-export-to-pdf generates \\\relax everywhere instead of \\.

At least in tables, this seems to be erroneous as both latexmk & pdflatex complain and removing the \relax in the generated ".tex" file suffice to render them compilable again.

Is that a bug or is there something I missed?


Cheers,

  
Guillaume MULLER
