From: David Kastrup <d...@gnu.org> Try deleting C:/Program Files/lilypond-2.23.6/lib/guile/2.2/ccache/ice-9/eval.go
which sounds like an outdated compilation cache (though I have no idea why). That fixed it. From: Jean Abou Samra <j...@abou-samra.fr> Which is the one you were able to run? For 2.23.6, the binaries from GitLab use Guile 2, while the ones from lilypond.org use Guile 1. This is clear-cut. Running 2.23.6 from lilypond.org I could not provoke the problem in two dozen runs (the maximum I got clear with 2.23.9 was one dozen runs), but my first run with 2.23.6 from GitLab displayed it. I see no need to go back to 2.23.5 or 2.23.4. Paul
