Failing to auto-compile

[fiat96]

Hello! I am using TeXLive 2020 and Lilypond 2.20.0-1 on Windows 10.

I've been trying hard to get lyluatex to work properly, and I've run up against one last problem. Any music in my .tex file has to be manually complied once or twice to show up in the pdf.

Here's an MWE:

\documentclass{report}
\usepackage{lyluatex}

\begin{document}

Here's some music: \lilypond{a b c}

\end{document}

Compiling this brings up this error:

? 

I notice it looks for and fails to find a .aux file. The .ly file produced in /temp-ly is perfectly fine, but the .log file is empty.

If I compile the .ly file in /temp-ly, it produces a pdf file that is exactly correct.
Compiling the .tex file a second time produces a good pdf, but with the following warning:

Module lyluatex Warning: gs couldn't be launched; there could be rounding error
s. on input line 6

Larger files seem to get stuck while compiling the temporary .ly file. If I manually compile it while the second tex compilation is trying to compile it, the correct pdf is immediately produced. The gs launch warning above still occurs.

For the record, this is occurring whether I use TeXworks, TeXstudio, or command line; and whether I use \lilypond, \begin{lilypond} ... \end{lilypond}, or \lilypondfile.

Adding [force-compilation] when calling lyluatex does not help.

Any assistance is greatly appreciated. Thanks!

Please share the generated tmp-ly/e7131d1ccea7db24b4bb2261f5f50848.ly file as the messages indicate that LilyPond tried to compile that and failed.

However, the other hint is that "The filename, directory name, or volume label syntax is incorrect." This may mean that our code to let LilyPond find the file to compile may be incorrect and fails to work properly on Windows.
Could you please also show a command line that lets LilyPond correctly compile the temp file?

[fiat96]

Okay, here's the tmp-ly/e7131d1ccea7db24b4bb2261f5f50848.ly file:

%%File header
\version "2.18.2"


\include "lilypond-book-preamble.ly"

#(define inside-lyluatex #t)
#(set-global-staff-size 11.111111111111)

\header {
    copyright = ""
    tagline = ##f
}
\paper{
    system-count = 0
    
    two-sided = ##f
    line-width = 345.0\pt
    indent = 0\pt
    
    
}
\layout{
    



    
}


%%Follows original score
{a b c}

And this temp file compiles fine with just
lilypond tmp-ly\e7131d1ccea7db24b4bb2261f5f50848
in the command line running in the Documents folder.

I don't know if this may help pin down the problem, or just muddy the waters...

I tried to compile the file on an older computer which is running TeXLive 2016 and Lilypond 2.19.3 on Windows 7. I realize that's changing all the variables at once...

The interesting thing, though, is that the file would not compile in the command line, but it did compile just fine in TeXworks. The command line also produced a different type of error:
