Just to be sure. You did install the version from OpenRepos? As the version from the Jolla Store doesn't have haptic feedback (/vibrations).

If you did install from OpenRepos, it might be that something goes wrong in starting the vibration, which makes the rest of the code fail.

You might be able to get some information from the normal program output. This can be seen by for example starting Kodimote from the terminal, "/usr/bin/harbour-kodimote". But I can't promise that I will be able to fix anything without having a SFOS 2.0 installation to test.
