I opened this file:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{amsmath}
\usepackage{tikz-cd}
\usepackage{luatex85}
\begin{document}
$a+b$
\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% TeX-engine: luatex
%%% End:
--8<---------------cut here---------------end--------------->8---

hit C-c C-p C-d, answered with n when asked for caching the preamble,
and it works as expected.  Can you give a more precise recipe how to
reproduce this?

Best, Arash
