Thanks, that shows the issue, the driver crashes for an error in the base library:

[2022-12-31T22:24:21.884 CET DEBG ][ org.kde.kstars.indi] - INDI Server: "2022-12-31T21:24:21: Driver indi_scopedome_dome: Impossible ISState 81"

This is probably an uninitialized variable coming from somewhere (the valid values are 0 and 1), which would be easy to find with a debugger and breakpoint at the error print in sstateStr function in indidevapi.c. If you can do that if would help a lot, but I can try to pinpoint the source as well. If you could enable driver debug logs as well, it might help narrow it down. My own dome has the older USBCard 2.1 controller so it's better tested, but I have the Arduino controller at hand too, though not connected to actual dome.
