This is the same issue I'm having. I can start the sequence by looping exposures while still pointed at the sky. As soon as i place my flats panel on the scope, the first sub that comes in forces the app to crash. It seems the sudden change in light intensity causes the FITS viewer to crash and drag down Kstars with it. (This is whats causing my issues explained i another thread, when I reconnect the camera maintains -20°C even though the cooler is reported as OFF). A fix is to start with low light intensity and work up to a brightness/exposure that generates the correct histogram/ADU value. If i then switch off the FITS viewer I can run the flats plan without issue.
