Please change "/dev/null" in line 262 of  C:/Program Files(x86)/LilyPond-2.23.4/usr/share/lilypond/current/scm/lily/framework-cairo.scm to the equivalent of /dev/null on windows. What name is used for the NullDevice in the supported Windows versions? \Devices\Null? Null? 

Background: ly:make-paper-outputter assumes that every backend will need an output file,  I thought choosing /dev/null would be ok as (most of) the output files are  created, written and closed directly by the cairo library.
