Krish,

I looked at log _21-01-21.txt and see:
[2023-05-29T21:07:53.704 AEST DEBG ][ org.kde.kstars.indi] - ZWO CCD ASI1600MM Pro : "[DEBUG] ASIGetExpStatus failed. Restarting exposure... "
[2023-05-29T21:07:53.705 AEST DEBG ][ org.kde.kstars.indi] - ZWO CCD ASI1600MM Pro : "[DEBUG] StartExposure->setexp : 1.000s "

On my system I get similar failures consistently after 17 exposures if I run with the firs viewer enabled. If you are using the viewer, try disabling it in the KStars settings, to see if that helps.

On whether the roof driver is involved, it is not an obvious suspect. It does though appear to be having problems during the initialization and indicating roof closed during the test.
