After update TeXLive on 18.10.2022 (all packets) I get problem with xelatex
compilng this combination:
\documentclass{article}
\usepackage{lettrine}
\usepackage{polyglossia}
\setotherlanguages{hebrew}% <- problem with this string
\begin{document}
Test
\lettrine{T}{est}
\end{document}
There is no problem with other language, like greek, russian etc, but only with hebrew.
LuaLatex
compile it without problem.
All worked fine several month ago (at June this year).
