My previous messages seem to have vanished. I have looked at the code,
and identified the issue. This was a one-word typo in one function,
which has now been corrected and sent to CTAN. It will take a few days
to propagate to MiKTeX, but for the moment you can use

\usepackage{expl3}
\ExplSyntaxOn
\cs_set:Npn \bool_until_do:nn #1#2
  {
    \bool_if:nF {#1}
      {
        #2
        \bool_until_do:nn {#1} {#2}
      }
  }
\ExplSyntaxOff

before loading fontspec.
