On version 1.16.0 from TeX Live distribution version 2023 using LUALaTeX 2023.8.28. It appears when `\usepackage{babel}` is modified to `\usepackage[arabic]{babel}`<br>
<br>
>From what I understand LUATeX use by default UTF-8 and using inputenc will conflict with it because it tries to re-define the encoding which is locked in LUA/Xe, so will end up in a "crash". So Babel (or whatever invoke it) shouldn't do it (I think it tries
to use cp1256 here, despite not asking for it) when not using PDFTeX (or whatever needs it), like on that case. And worse, some calls takes priority so re-using inputenc to ask for UTF-8 won't correct the problem because it takes the first call only</div>
