Try this:

\version "2.22.2"

<<
  \new Staff \fixed c' {
    \time 2/2
    \set Staff.baseMoment =
      #(ly:make-moment 1/4)
    \set Staff.beatStructure = 1,1
    b8 d' c' b
  }
  \new Staff \fixed c {
    \time 2/2
    \clef bass
    e8( <gis d' e'>) q q
  }
>>



I suspect you were doing \set Timing.baseMoment = ...
and \set Timing.beatStructure = ... as shown in the
documentation. Unless you use polymetric notation, Timing
is an alias for Score (the context where timing is managed),
so these \set commands make global settings, whereas
you want them on Staff level.
