Bit of a strange one. This issue was happening on the previous Kstars and again last night on the latest release.

I'm using an ASI1600 and Stellarmate run off an RPi4 4GB and monitor over VNC. Everything is fine 95% of the time. If I'm in the middle of an image plan and I pause it or stop it, for example, I'm not happy with an autofocus result and I pause the plan to focus again, Kstars will close unexpectedly without warning. It's happened a few times now. The strange thing is, the camera cooler keeps running even after Kstars crashes. When I start it up again, I connect everything as normal. At first I was starting the cooler but I noticed the the ammeter on my PSU was rising an amp for a few seconds and then dropping off again for a few seconds. The temperature would fluctuate between -18 to -21 repeatedly when it should be at -20. I found out that if I switch the cooler off after a crash it remains at a steady -20 which is the temperature the camera was set to before the crash. Ekos reports that the cooler is running at 0%. Pics attached. Any ideas why its crashing in the first place?
