Right... when you haven't made any changes, the issue is almost always related to a specific target. In your case it's this:
ASCOM Telescope: Error in Slew : SiTech Says: InvalidOperation Slew Requires Meridian Flip! (ASCOM.InvalidOperationException: SiTech Says: InvalidOperation Slew Requires Meridian Flip!
Your mount is actively refusing the slew command because it thinks it will need to flip in order to point to the requested location.
SGPro cannot do anything about this, but we do need to handle this particular error more elegantly. I'll look into that.
