Well, I had replied to you two times, asking for further information. Since that didn't come I didn't look into it so far ...

What exactly is this, what is the prerequisite to compile your documents (since you're talking about an "coming upgrade").

When I use

\setmainfont[Renderer=Harfbuzz]{TeX Gyre Schola}

I get this error in *my* LuaLaTeX even without loading lyluatex

This is LuaTeX, Version 1.10.0 (TeX Live 2019)  (format=lualatex 2019.8.8)
...
! LaTeX Error: Missing \begin{document}.

So in order to track your issue I *really* need more information about the environment/context this is in.
