I just finished installing and updating TeX Live 2020 on Windows 10. I performed a full installation of TeX Live. Now, compiling this simple document:
% !TEX program = lualatex
\documentclass[a4paper, 10pt, extrafontsizes]{memoir}
\begin{document}
Text
\end{document}
I receive this error message:
This is LuaHBTeX, Version 1.12.0 (TeX Live 2020/W32TeX)
restricted system commands enabled.

How can I solve this problem? Thank you very much for your help!
tlmgr update -all
, I receive this message: ‘tlmgr.pl: no updates available’. If I runtlmgr update --self
, I receive this message: ‘tlmgr.pl: no self-updates for tlmgr available’. Andtlmgr search l3backend
returns ‘l3backend - LaTeX3 backend drivers’. How can I check about the formats?kpsewhich --all -engine=pdftex pdflatex.fmt
probably reports two formats
