fontspec error (cannot resolve fontname of NewComputerModern)

[Robert Alessi]

Hello,

With lualatex (or xelatex), I can't compile this file anymore:

--------------------snip--------------------
\documentclass{article}
\usepackage{fontspec}
\setmainfont{NewComputerModern}
\begin{document}
Hello.
\end{document}
--------------------snip--------------------

I get this:
! Package fontspec Error: The font "NewComputerModern" cannot be
found.

However, luaotfload-tool --find "NewComputerModern" returns:

luaotfload | resolve : Font "NewComputerModern" found!
luaotfload | resolve : Resolved file name "/usr/local/texlive/2021/texmf-dist/fonts/opentype/public/newcomputermodern/NewCM10-Book.otf"

Does anybody have an idea on what is going on?

Thank you,

Robert
