It does not work on my Mac with texlive-2020, so I export my org file, 
open it and replace
all occurrences of \\\relax with \\ before compiling.  I have to confirm 
this on Gentoo Linux
with texlive-2022 at work.

I think that \\ signals the end of a table row and that \relax ends up 
on the next row with
missing fields.
