Por alguna razón, la inclusión del paquete fontspec hace que XeLaTeX no se compile correctamente.
Aquí hay un MWE (inspirado en Rob Hyndman):
\documentclass{article}
\usepackage{lipsum,fontspec}
\begin{document}
\section{Introduction}
\lipsum[1]
\section{Main}
\lipsum[1]
\end{document}
Si elimino el paquete fontspec, todo funciona bien. Con él, recibo muchos errores y el PDF resultante tiene el siguiente texto encima:
require(’luaotfload-main’) local v oid = luaotfload.main()
require(”fontspec”)
EU2

SOLUCIONADO: Según los comentarios de egreg sobre paquetes obsoletos relacionados l3packagesy otros, desinstalé estos paquetes en el administrador de paquetes y luego eliminé las subcarpetas de estos paquetes de la carpeta MikTeX. Volver a compilar ahora produce un PDF perfecto (incluso cuando se usa \setmainfont{Georgia}).
¡Gracias a todos!
