troubleshooting a non working ASI533 under SGP with a user we got the announcement from Main Sequence Software that you must select the ASI camera (ASCOM) under the equipment tabs not the native ZWO driver.
Native driver is no longer supported it seems :(
if you have issues in SGP using ZWO cameras then make sure you have selected the ASI (1) or ASI(2) driver not ZWO Camera
