[MU4 Issue] muse-hub-service crashes and relaunches every few seconds

Describe the bug I've been trying to find out why muse-hub fails to launch on my system (KDE neon--details below). Watching the task manager, I see the "Muse.Service" and "muse-hub-servic" processes starting and then quickly crashing, then starting again, etc. forever.

Each time this happens, the following gets printed to the Linux system log:

The Affected System (Desktop PC) OS: KDE neon User Edition (based on Ubuntu 22.04) Muse Hub version: 1.0.0.392 (deb package) CPU: Intel Core i7-990x Gulftown (3.46 GHz hexa-core, Socket 1366) @ 4.15 GHz RAM: 24GB (6x G.Skill 4GB DDR3 PC3-10666 1333 MHz) @ 1430 MHz

I don't believe the issue is KDE neon, as I have been able to get Muse Hub to work on two other setups using this same operating system with all software up to date. One working setup is my laptop, and the other is a Virtualbox install running on the desktop PC listed above. Despite eventually getting Muse Hub to run on those two systems, it would not launch the first time I tried. In each case, I alternated launching Muse Hub from the application shortcut and the terminal until it finally started up after a few tries.

Looks like some weird .NET error, I'm not using the configuration system, so I'll see if I can disable it so this error won't appear for you.

Thanks, Dominic! Is this something I just need to wait for an update on, or is there upstream code I can test somewhere?
