I had problems with a basic ly file. It looks like the program is
trying to open /dev/null and that doesn't work on a windows machine.

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.
Also, just a note, my windows system tried everything it could not to
let me download and run the LilyPond file. Google Drive, Google
Chrome, Windows, and Norton all tried to stop the process.
