This change was intended, see the top entry at

http://lilypond.org/doc/v2.23/Documentation/changes/index.html

To get the old behaviour, also move the
Mark_tracking_translator, like this:


\version "2.22.1"

\layout {
  \context {
    \Score
    \remove Mark_engraver
    \remove Mark_tracking_translator
  }
  \context {
    \Staff
    \consists Mark_engraver
    \consists Mark_tracking_translator
  }
}

<<
  \new Staff { \mark \default c'1 }
  \new Staff { c'1 \mark \default }
>>
