Problem solved by changing the following things:
1.) Switched the Source Extraction Method for my Local Astrometry solver to Builtin method for solver.
2.) Instead of taking RAW images with my Canon camera for polar alignment I took Medium Fine JPEGs.
Still don't understand why, but using the above settings I have no more force close of KSTARS v3.5.5 on polar alignment.
Maybe this helps also others.
Thanks for hint, I'll try to polar align using my guide scope and ASI120MC camera.
BTW I am using my own Cygwin build of astometry.net for plate solving which works perfectly (not only in EKOS, but everywhere).
Anyway, I think force close of an application is a quite serious problem which should not happen...
I was able to reproduce the same crash issue using CanonDSLR and TelescopeSimulator drivers (while still on KSTARS/Windows v3.5.5).
Interesting that when I switched to CCDSimulator + TelescopeSimulator, the problem did not occur and polar alignment routine worked.
I think the problem is more or less connected to the combination of CanonDSLR driver and KSTARS/EKOS-Windows v3.5.5.
BTW my camera (Canon EOS 1300D) parameters are:
Max. resolution: 5184 x 3456
Pixel pitch: 4.29 µm
I have the following setup:

This is not for Stellarmate OS, but for Ubuntu Mate 20.04.1 LTS (Focal Fossa) 64bit, but maybe helps to someone.
The reason why on this system the execution of start.sh fails with No such file or directory is simple:
Firecapture v2.6 is a 32bit application and by default it is not allowed to execute on 64bit OS.
To enable Firecapture v2.6 on 64bit Ubuntu Mate we need to run following from command line:
sudo dpkg --add-architecture armhf sudo apt-get update sudo apt-get install libc6:armhf libncurses5:armhf libstdc++6:armhf libxext6:armhf libxrender1:armhf libxtst6:armhf
The same here.
Tried to update my opening post with your info about the risks of that approach, but somehow the forum does not allow me to edit the post. Anyway thank for info and explanation.

I merely wanted to point out the risks of doing it this way. It is good to know that a workable system can be created by using the PPAs on Debian. Fingers crossed that this keeps on working in the future but unfortunately I wouldn't be surprised if it didn't.
EDIT: By the way I am not trying to point fingers to anyone about this. I am merely trying to state that it requires a lot of effort. Which should make all of us realise the tremendous amount of work going into this free-of-charge project for which I am very grateful!!!
