Try the workaround given here:

https://gitlab.com/lilypond/lilypond/-/issues/3766#note_623977182


\version "2.22.1"

#(define (Tuplet_accidental_support_engraver context)
   (let ((brackets (make-hash-table))
         (ending-brackets '())
         (accidentals '()))
     (make-engraver
       (acknowledgers
         ((tuplet-bracket-interface engraver grob source-engraver)
            (hashq-set! brackets grob #t))
         ((accidental-interface engraver grob source-engraver)
            (set! accidentals (cons grob accidentals))))
       (end-acknowledgers
         ((tuplet-bracket-interface engraver grob source-engraver)
            (set! ending-brackets (cons grob ending-brackets))))
       ((stop-translation-timestep engraver)
          (hash-for-each
            (lambda (bracket dummy)
              (for-each
                (lambda (accidental)
                  (ly:pointer-group-interface::add-grob
                    bracket
                    'scripts
                    accidental))
                accidentals))
            brackets)
          (for-each
            (lambda (bracket)
              (hashq-remove! brackets bracket))
            ending-brackets)
          (set! accidentals '())))))

\layout {
  \context {
    \Voice
