If you're using Stellarmate, then please reach out to the Stellarmate support and they can help you identify the crash.

If it's KStars and I have a little down time, I can try and reproduce the crash--I only run on Linux here, so hopefully it would reproduce on Ubuntu 22.04.

Please make sure you can repeat it, then send me:
- the fits file you used to crash the system (was it one of those you already sent?)
- the log file
- which OS/computer you're using,
- which version of KStars
- assuming linux, please send ~/.config/kstarsrc ~/.local/share/kstars/userdb.sqlite

Thanks,
Hy

PS If you are a programmer--e.g. this makes sense to you--please also do this
- run kstars under gdb
- when it crashes get a stack trace with the bt command

I tested KStars with online astrometry and it worked fine right away. Did you put your API key in the config?

I can confirm I jave used my own key for online astrometry. And yes I am using stellarmate OS.
