"Programming error" bug?

[David Sumbler]

I have just started on a new Lilypond project, having had little interaction with Lilypond for several months.  I installed v.2.23.4.

Although I have so far only set 3 lines of music on 2 staves, the message "programming error: cyclic dependency: calculation-in-progress encountered for #'adjacent-pure-heights (VerticalAxisGroup)" is issued 8 times when compiling.

From the very little I could find searching online, it seems as if it might have something to do with my having moved Mark-engraver etc. from their usual context.  It was also suggested that this is a bug.

Is there some way of suppressing these messages?  I know how to suppress warnings, but that won't work with these error messages.

The code I am using to set up the "staff" containing metronome marks etc. is:

\layout {

  \context {

    \name "MarkLine"

    \type "Engraver_group"

    \consists Output_property_engraver

    \consists Axis_group_engraver

    \consists Mark_engraver

    \consists Metronome_mark_engraver

    \consists Text_spanner_engraver

    \override RehearsalMark.extra-spacing-width = #'(0 . 1)

    \override MetronomeMark.extra-spacing-width = #'(0.5 . -inf.0)

    \override TextSpanner.Y-offset = #3.5

    \override VerticalAxisGroup.minimum-Y-extent = #'(-2 . 2)

    \override VerticalAxisGroup.staff-staff-spacing =

    #'((basic-distance . 1)

       (minimum-distance . 1)

       (padding . 1)

       (stretchability . 3))

  }

  \context {

    \Score

    \remove Mark_engraver

    \remove Metronome_mark_engraver

    \accepts MarkLine

  }

}

I can't remember where I got this code from.  Is there something that needs to be changed in it?
