Looks like the edition-engraver doesn't like injecting
\newSpacingSection. By the way, it has nothing to do with
2.23.6, also happens in 2.22. As a workaround, you can
replace \newSpacingSection with

#(make-event-chord (list (make-music 'SpacingSectionEvent 'dummy 'dummy)))

It seems that LilyPond does an inappropriate type check on
the second argument of ly:make-stream-event (pair? instead
of cheap-list?), but it also looks like edition-engraver is
missing some bits. I don't have the time to look more closely
for now, maybe later, or maybe someone else will do it.
