Ouch, that looks like a variant of
https://gitlab.com/lilypond/lilypond/-/issues/6474

As a workaround, try putting this in a file called ".guile"
(note the leading dot) in your home directory:

(use-modules (system repl common))
(repl-default-option-set! 'interp #t)


Or instead of using "lilypond scheme-sandbox", use
"lilypond my-scheme-sandbox.ly", putting this in
the file "my-scheme-sandbox.ly":

#(use-modules (system repl common))
#(repl-default-option-set! 'interp #t)
\include "scheme-sandbox.ly"

HTH,
