Hi Fabio,
First I'd suggest that you let it run for longer. Just-in-time compiling
can take a while, so if you stopped the process within 20s or so, assuming
there's inactivity, you might have missed the output. Also you can try
running it in a command prompt like PowerShell, so that it does not close
immediately after finishing.
If you waited long enough and it does freeze there, then you could try two
things. Open the demo file and change verbosity to debug
(DEMSim.SetVerbosity("DEBUG")), re-compile and re-run and let us see where
the freezing happens. Or better, just try compiling and running it in WSL
to see if it works. Windows now comes with WSL and installing it is as easy
as one line of command. It's likely to work fine in WSL and if not, it's
probably about the environment or the hardware.
Thank you,
Ruochun
