Brief outline of the issue

With a recent (2024-06-01-ish) release of LaTeX, use of the bidi package seems to break nicematrix >= 6.28. According to the discussion at Issue latex3/latex2e#1368, this may be because the array package, whose definitions bidi redefines, was recently changed.

I also reported this issue by e-mail to the nicematrix maintainer.

Minimal example showing the issue

\documentclass{article}

\usepackage{nicematrix}
\usepackage{bidi}

\begin{document}
\begin{NiceTabular}{lllll}
a & b & c & d & e \\
\end{NiceTabular}
\end{document}

Expected behavior

The minimal example should compile, but instead produces the following error message:

(./test.aux) (/opt/texlive/2024/texmf-dist/tex/latex/base/ts1cmr.fd)
! Extra alignment tab has been changed to \cr.
<template> \endtemplate

l.9 \end{NiceTabular}
