I think you have done everything you can.
My best guess is this is what is happening.
UMS is trying to write to a part of your memory which is normally free but in your case is being used. Any part/item of the hardware on your computer could be using that memory space.

In the valgrind test there is ...

I installed and ran valgrind on my system. It ran without any errors or warnings.

The output from your test had:
==24351== WARNING: new redirection conflicts with existing -- ignoring it
--24351-- old: 0x04028b00 (strlen ) R-> (0000.0) 0x580c2e1a ???
--24351-- new: 0x04028b00 (strlen ) R-> (2007.0 ...

There is a package called valgrind(I haven't used it) which can give more info with malloc errors

Usage,:
valgrind ./your_program_name

I don't know what else I can suggest.
Discounted RAM as an issue.
We know it works with Mint 22.3 as it works on your laptop.
You have reinstalled Mint on your desktop.
The only thing left is the hardware difference between your laptop and desktop.

@mik_s. Maybe one fore the developers?

Try
grep "mailoc()" /var/log/ -r
It will take a while as that searches all the logs.

Does your desktop have a video card as well as an on board video.
Video cards have been know to cause some strange memory issues.

Try
grep "mailoc()" /var/log/ -r
It will take a while as that searches all the logs.

You have tried all the combinations so that discounts a RAM error.

I'm stumped and don't know where to go from here.
Apart from a reinstall of Mint I can't suggest anything else.

Maybe @mik_s can spot something comparing the logs.

Let us know how the individual RAM goes.
Nothing sticks out comparing the debug.log files from 22.3 on your desktop v 22.3 on your laptop.
Maybe @mik_s can spot something.

I did my install on Gentoo Linux.
The only reason I wanted to try and get Mint 21.3 computer working was to try and nail down if the problem was something specific to your Mint 22.3 computer.

If you did want to try and get UMS working on you Mint 21.3 computer:
Use the /home/david/.config/UMS/UMS ...

Re: VLC
Sorry, vlc-nox is the older unmaintained version ov VLC.
vlc-bin is correct.

UMS does have its own ffmpeg but UMS.conf has to be configured to use the inbuilt ffmpeg.

I don't remember UMS adding the shares (Music, Videos, Pictures) in the users home directory for myself.
I did a fresh ...
