Running KStars 3.4.3 stable, ubuntu 20.04, Intel NUC
It has been happening on my system for a long time.
Sometimes KStars crashes during initial startup it seems happen around the time 6 of the 9 top level Ekos icons have been displayed. Retry a time or two and it will get through the startup and run okay so it has not been a big issue.
Ran it today using ekos-debugger and got the attached files.
