I'm using TexLive running Xelatex on Arch from Neovim with Vimtex, all the latest version.
I haven't used LaTeX for a while and after a full system upgrade, I'm noticing some problems with my current LaTeX build. Most of them, like "latexmk is not an executable" due to TexLive being restructured are already solved, but I have yet to solve problems like this that I don't know where to start.
\documentclass{article}
\begin{document}
Curly ``quotes'' on Austro--Astrophotography---here.

I found in line 13 something is not found. Could it be the problem?
