Application: kstars (3.5.6 Beta)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.11.0-37-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Kstars and Ekos
goto target worked,
alignment on target worked fine,
solver worked fine for alignment.
next step was to start guiding, and it crashed when I clicked on "guide".   it did this repeatedly.
I rebooted the system also and it still did it.

May have something to do (again) with ASI camera and 8-bit mode vs 16-bit mode. ..  had trouble in the past with this, and that was fixed, but tonight the camera flipped over to 8-bit mode again all by itself (or something did. I didn't tell it to change from 16-bit).  
I changed it back to 16-bit.

'guide' had worked earlier tonight.

next test is to completely power-cycle everything including cameras.
if you get another bug report, that didn't fix it either.

The crash can be reproduced every time.
