That snippet was the actual error context so you have to read it
upside down, and there is a bit of information missing. The
general overview is:
\makebm expands into something containing
\bm that expands into something containing
\bm@command that expands into something containing
\bm@gr@@p that expands into something containing
\bm@mchoice that expands into something containing
\makebm ... (full circle)

It seems \makebm is an internal macro of the bm package, and the
document-level definition of \makebm to redefines that macro.
Perhaps this is the result of a recent update of the bm package.
At least that would explain why the documentation may have been
run with errors in the past.
There is a simple solution: use a different macro name for the
in-document definition.
Best wishes,
Taco
