Actually, I'm not surprised by the error message.  Your input code can
be reduced to the following, also shown in the attached image.

```
\version "2.24.0"

<<
  \new Staff { \stopStaff
               f'1 | f'1 }
  \new Staff { R1  | R1  }
>>

\layout {
  \context {
    \Score
    \remove Bar_number_engraver
  }
  \context {
    \Staff
    \consists Bar_number_engraver
    \override BarNumber.break-visibility = #all-visible
  }
}
```

As can be seen, there are no bar lines available in the first staff,
which are needed for the bar number engraver to vertically position a
bar number.  Of course, the error message is cryptic, and my
interpretation might just be an educated guess – but I believe that a
error message is OK for this situation.

What do you *really* want to achieve?
