I get some errors: version 2.23.0a lot of Unsupported SCM value for format (various values that look like 0.287106 -0.72778135 )
These error messages are probably due to the internal changes that were made to LilyPond stencils between v2.20.4 and v2.20.5.
The file cowell-clusters.ly uses ly:make-stencil in two places. You will find comments inserted there, telling you how to cope. Cheers, Robin
