Hello,
It looks like #6093 but it has been fixed and closed (and I don't
understand the ins and outs of the discussion between developers).
https://gitlab.com/lilypond/lilypond/-/issues/6093
Previously, you needed \override Stem.neutral-direction = #'()
to signal that you allowed LilyPond to set the neutral direction
itself. This did not work well because the Melody_engraver does
not do this in all cases, like for rests. That left the rest's
stem (yes, it exists) without a direction. If something (like a
tuplet) requested the direction, that could go wrong. This one
appears to have worked by accident. In 2.23,
- Warnings have been added for this, so while this worked
for the wrong reason before, it now warns.
- The override has been made unnecessary.
The solution is to simply remove it.
Best,
Jean
