luainputenc is only for lualatex. If you want to compile with pdflatex, use inputenc instead. When compiling with lualatex, however, \usepackage[utf8]{luainputenc} is unnecessary because UTF-8 is already the default. If you want to be compatible with all three major engines, use a switch like the following:

\usepackage{iftex}
\ifPDFTeX
\usepackage[utf8]{inputenc}
\fi
