Dear John,

If you change

\repeat unfold 4 { ""1 }

to

""1*4

like in the attached example, the measure compression appears to work.

Does this fix the problem?

Bug Demo copy.ly (text/plain, 1015 B)

% This LilyPond input file demonstrates a bug involving the
% \compressEmptyMeasures and \compressMMRests commands.
% The song has lyrics that don't start immediately and a
% bass guitar part that doesn't start immediately.  If the
% lyrics are removed the \compressEmptyMeasures and
% \compressMMRests commands then work.


\version "2.24.1"


bassgtrnotes = \fixed c, {
  \compressEmptyMeasures    % I have tried both of these statements
  %\compressMMRests 
  {
  \override MultiMeasureRest.expand-limit = #2
    R1*4
    b,4 b,4 b,4 b,4 |
    
  }  % end of \compressMMRests
  
}


words   = \lyricmode {
   ""1*4    % ""1 represents a whole measure of silence
