Equipment: rPi4b 4GB, Astroberry, KStars updated to 3.5.0, CEM25p, WO Z61, Canon 700D, no guide scope or focuser.
KStars and Ekos always crash to desktop toward the end of the Polar Alignment routine. The 3 images all solve correctly (the new solver works like a champ - thanks to whoever programmed that!). The console reports "Please wait while WCS data is processed", followed shortly by a full shutdown of KStars.
I have attempted the Polar Align about 10 times since moving to the rPi. It did once get as far as showing the results and correction vector, but crashed (not to desktop, frozen) while I was fiddling around trying to get the information large enough to read on my laptop's high-dpi display). For now, I'll settle for solving the post-WCS crash issue.
Here is the tail end of the log, a full log is attached. Pl
ease let me know if I need to turn on additional logging options.
