[2023-01-27 12:30:06] [INFO][net.sourceforge.ganttproject] [GanttOptions] save(): finished!!

I updated the same patch on a M1 Mac, and Gantt won’t work at all anymore. I tried deinstalling, downgrading to 3.2.3247, re-installling 3.3.3290, but to no avail. Whatever I do, Gantt won’t start up anymore. It just shows the splash screen, but nothing happens. What can I do to get it working again?
