This is caused by fontspec, I'd say, due to somewhat recent changes in
the expl3 supporting package: \c_keys_code_root_tl was renamed
\c__keys_code_root_tl at some point, to reflect its internal nature,
and fontspec should not be using it.  I don't know if this was fixed
in more recent versions of fontspec (it seems to be).  I've added the
maintainer in Cc.

In the mean time, a temporary (ugly) workaround is to add

  \csname c_keys_code_root_tl\endcsname *
  {\csname c__keys_code_root_tl\endcsname}

early in your document.

Best regards,
