A bit of a change in the behaviour, though probably meaningless.
Even before installing the debug version, I tried running 2018.06.03.1 with Win8 compatibility, but same result. Then I tried Run as Administrator, and this time it simply terminated by itself, rather than hanging.
The debug version also just terminated the first time I ran it, the console window closed by itself. The second time it hung, with the console still open, and showing this:
no file 'C:\Program Files\Hybrid\misc.ini' found,..
no file 'C:\Users\bxf99\.hybrid\misc.ini' found,..
No misc.ini file used,..
using scaling mode: 0
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
QT_SCREEN_SCALE_FACTORS to set per-screen factors.
QT_SCALE_FACTOR to set the application global scale factor.

This last line is also what I see under the logo when the normal version hangs.
Good night and good luck.
