I am unable to load images into a stack with v 22.0. I have a laptop with 2 graphics cards, windows 10. The nvidia card is set in windows for this and older versions of photoshop. When I have graphics card selection turned off in preferences or when it is on and set for basic, photoshop loads 1 image and stops, the thumbnail is white. When I use normal or advanced, the screen strobes with bright white. I have tried with the intel graphics card deactivated as well as on. I have tried with alternate images to be stacked, same prob. Thanks.
