Hi Steve,
sorry for not replying earlier.
Great that you managed do get a backtrace.
The backtrace points to a problem within Guile, the Scheme interpreter
Lilypond is built upon.
We currently do not release Lilypond for Windows ARM, because
setting up the compilation environment is far from being trivial
and the Windows support in Guile (speaking about x86_64) is buggy and fixes
get upstreamed very slowly. AFAICT, no one is working on Windows ARM
support for Guile at the moment.
That said, x86_64 Guile should run in the emulation layer and it
should be possible to find out why it does not.
Unfortunately I currently have very little time to help you.
What I would like to do is sending you a self-contained Guile executable
compiled against the newer Windows C runtime (UCRT) to see
if the problem persists and/or verify that the problem is not a subtle
issue within the Lilypond-Guile interface.
Not sure when I will manage to do this, though.

Hello,
Did the WinDbg output help? Is there anything else I can provide?
I noticed that 2.27 dev was released and saw there were ARM versions listed for
MacOS but none for Windows. ☹
Thanks,
Steve

I'm not very familiar with WinDbg but I installed it from Microsoft Store and I
think I managed to run lilypond with command line arguments to process
testscore.ly.
I tried to disable the JIT compilation as well, here's what I tried -
set GUILE_JIT_THRESHOLD=-1
C:\Users\steve\AppData\Local\Microsoft\WindowsApps\WinDbgX.exe -o -g
-G
"C:\Users\steve\AppData\Local\frescobaldi\frescobaldi\lilypond-binarie
s\lilypond-2.26.0\bin\lilypond.exe" -o testscore.pdf testscore.ly
WinDbg output attached.

Thanks,
your attached file shows exception code 0xC00000FF ->
'STATUS_BAD_FUNCTION_TABLE'
which means 'A malformed function table was encountered during an unwind
operation.'

Can you try to run lilypond through WinDbg?

There is not any popups or anything other than that return code. I’ve reviewed
the entries in Event Viewer several times while testing this but nothing ever
showed there.
The only thing I can ever find is in

When it crashes, do you get a popup that would allow you to get a
stack trace / crash report? These might just be hexadecimal numbers

And if there is no popup, check Windows Event Viewer. There are separate logs
for System and Application, either could be interesting.
