Making Abjad output a file

Question

I'm trying the abjad library for python for the first time, but I'm not able to make it create neither lilypond nor pdf files. This is the error showing in the console every time I run it:

PS C:\Users\giuli\Coding\abjadExperiments>  & 'C:\Users\giuli\AppData\Local\Programs\Python\Python311\python.exe' 'c:\Users\giuli\.vscode\extensions\ms-python.python-2023.20.0\pythonFiles\lib\python\debugpy\adapter/../..\debugpy\launcher' '51354' '--' 'c:\Users\giuli\Coding\abjadExperiments\Abjad experiments.py'

                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [WinError 2] The system cannot find the file specified

I've tried to go in abjad's configuration file (abjad.cfg) and I specified the lilypond path in this way:

# Lilypond executable path. Set to override dynamic lookup.
lilypond_path = C:\Program Files (x86)\LilyPond

But it doesn't seem to do anything really.

But I'm pretty convinced I'm mistaking something very banal that I'm not aware of. Can you suggest some solutions?
