Systray Icon issues, possibly related to fan stoppage.

Device manufacturer
GPD

Device model
GPD Win Mini 2024

Handheld Companion Version
0.21.4.1

Describe the bug
Tray icon does not work with quad monitor (internal monitor @60Hz + 3x 4k @60Hz). Handheld Companion keeps running, but with neither anything visible in the system tray nor in the taskbar, nor anywhere in 'task view'.

Apparently the fan can stop in this situation, at least on occasion if the eGPU is unplugged and replugged, possibly only if Handheld Companion autostarts with Windows while the eGPU has been plugged (through the USB-C connector) in shortly before MSWindows booting gets to the login screen.

To Reproduce
Plug into external PCI-E Thunderbolt/USB4 dock with NVIDIA graphics card and 3x 4k @60Hz.

Try to do anything (starting app, closing, etc) that should show tray icon.

Expected behavior
Tray icon shows up.

Because fan stoppage is possible, I suspect this other bug is related:
#1169

Because this bug seemed a regression, not having been previously observed over a long time with a previous version of Handheld Companion, which I think is the same 0.21.4.1 version or very close to it, I suspect different versions of Handheld Companion have regressions in reading or writing settings. That is to say, I think there may be an error in the parser for saved settings somewhere. I tried erasing the %APPDATA%/Local/HandheldCompanion folder... but the fan profiles were still there and the systray issues still occurred...

From the behavior of Handheld Companion, I have also long suspected the GUI the program is based on is the cause of a lot of the bugs. Changing the software to use a different widgets library may be a better direction for future development.
