Ok, I can reproduce your problem on my current macOS environment
in the sense that I see the same pdflatex compilation problem &
trying lyx 2.4 for the original lyx file works.
The problem probably boils down to lyx 2.5 export change
-\texttt{\#pragma nooverlay\index{pragma nooverlay@\#pragma nooverlay}}~\\
+\texttt{\#pragma nooverlay\index{#pragma nooverlay@\#pragma nooverlay}}~\\
I am surprised though that it seems to work for Tobias.
I'll ask around on our lyx list.
