Windows: LilyPond EPS renders, but EPS-to-PDF conversion with Ghostscript produces empty PDF / parsecff rangecheck

Hi,

I recently took over maintenance of the LaTeX package lyluatex and noticed =
that
several users have reported issues on Windows with MiKTeX. I do not have a
Windows machine myself, but I tried to reproduce the situation using GitHub
Actions, and I hope I have gathered some useful information.

In short: I am seeing Ghostscript `/rangecheck` errors in `--.parsecff--` w=
hen
converting LilyPond-generated EPS files to PDF on Windows. The generated EP=
S
files appear to contain the expected music, but the resulting PDFs are empt=
y or
unusable.

My main questions are:
1. Is this a known version compatibility issue between LilyPond 2.26.0 and
Ghostscript 10.07.1 on Windows?
2. Which Ghostscript versions are expected/supported for LilyPond EPS/PDF
generation on Windows?
3. Should MiKTeX users pin LilyPond/Ghostscript versions, or configure
LilyPond font/resource paths explicitly?

Version info:
* LilyPond 2.26.0
* Ghostscript 10.07.1
* Windows Server 2022 GitHub Actions runner
* MiKTeX 26.5 present, but the minimal reproducer is outside lyluatex
