The problem in your example is this line:

\appendtoks\let\bibitem\itemgroupitem\to\itemgroupcommands

You assume that context has a \itemgroupitem command but this isn’t the case for a current beta where the internal command for \item has changed.

A save method for the english interface is \def\bibitem{\item}.
