SyncTrayzor silently died after starting in Windows 11

[nengxu]

SyncTrayzor 1.1.29 with Syncthing 1.18.5 running in portable mode.

I installed a customized Windows 11. SyncTrayzor worked fine for a while. Today I removed many fonts. Now when I start SyncTrayzor, its icon seems to be busy for short time. Then nothing come out. Neither SyncTrayzor.exe or syncthing.exe is running. I cleared all related log and tried again. Only SyncTrayzor.log has this:

As I just changed fonts, so my guess is SyncTrayzor is depending on certain fonts or icons. Or it depends on certain version of .NET? Of course, @canton7 you are the expert.

Something must have killed it hard. Open the Event Viewer -> Windows Logs -> Application, and look for Error entries. There are normally 2 for a .NET application crash.

I have not used Event Viewer. On a normal computer, I can't find the Error entries. On the failer computer, the windows search crashed. So it seems that my font change affected other things too.

After further investigation, SyncTrayzor seems to have the font Consolas hard coded. The FontSubstitutes mechanism of Windows is not obeyed. Could you please modify this behavior so when a font is not found, it will be replaced by font specified in Windows registry?
