A quick read of the HOWTO and I can say it will be very helpful.
I will work with it and come back with any ideas that may make it easier.
I have attached the log indi log files that show the crashes.
I am using Stellarmate 1.6 and KStars 3.5.5 Stable.build 2021-09-30T19:39:54Z.
I followed this for this link, from the iNSTALL, for the driver building process: indilib.org/forum/general/210-howto-buil...st-libindi-ekos.html
Then followed the INSTALL for the building the indi-rolloffino driver and associated files.
My Ekos Obs and Iindi Control panels are the same as your images.
