MinimWatch fails on Windows 10 Pro

[simbun]

I've finally moved to Windows 10 and I'm trying to get MinimWatch installed so I can control MinimServer on my Pi.
I've reinstalled Java and MinimWatch a number of times, and MinimServer on Windows 10 loads fine although I can't see it from BubbleUPnP.

$ java -version
java version "1.8.0_241"
Java™ SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot™ 64-Bit Server VM (build 25.241-b07, mixed mode)

Windows: Windows 10 Pro 1909

I've turned the firewall and SRP offf just to make sure I haven't got anything blocking it and I can open the Pi's status page using http://192.168.20.10:9790/
In Windows 10 my network is classified as a 'Private Network' with network discovery turned on.

When running MinimWatch, it flashes up in the taskbar but when I hover over it it disappears.

minimwatch.log

startup.log is empty

When running it from the command line, I see:

Is this something you've seen before?
Would you like the contents of hs_err_pid7728.log?
Are there any Windows services that it relies on?
