Problem in crop and automatic fill generation in camera raw 18.4.1

Cropping an image (sometimes some border parts are transparent pixels ) : when generative development sub-panel is rolled down(”generate” button lit in blue) generate fill starts automatically and it fails; when rolled up (“generate” button not visible), it doesn't automatically start. Seriously Adobe? Is this a software we pay money for? 

Please @adobe stop giving us meaningless new versions; we prefer tools that actually work to flashy Firefly options.
