If you are using fontspec it would try to load latin modern at
latest at the \normalfont command in \begin{document}.

I would recommend that you make better bug reports. luaotfload is
obviously working fine for quite a number of people, so there is
something special to your document or your system. A minimal
document and log-files are needed. You should also describe if you
tried to update the database manually and if this succeded (and if
not if you blacklisted all problematic fonts as described in the
manual).

luaotfload is about system fonts. So you should also mention your
OS.
