Lots of undefined control sequences when using Arabic Babel

On version 1.16.0 of LuaHBTeX from TeX Live distribution version 2023 using LUALaTeX 2023.8.28. It appears when `\usepackage{babel}` is modified to `\usepackage[arabic]{babel}`

It seems like he expects all commands to be written in Arabic, or maybe he has lost TeX definitions and don't know any commands anymore, or is misinterpreting anything. Anyway, many classic La/TeX commands are interpreted as unknown control sequences
