Unable to view images in Photoshop 22.11 on macOS Big Sur

Since upgrading to Photoshop 22.11, I have been unable to view a .dng image either by loading directly from Lightroom Classic 10.11 or by opening the file from my computer folder (Running Big Sur 11.1 on an iMac 27" with 24 GB of memory.

The image loads as normal into Camera Raw and the "Background Layer" is shown in the Layers Panel once Camera Raw has been closed. However, there is no sign of the image in PS and I am left with a black screen. If I enlarge the blank screen, only part of the image can be seen and, if the image is then scrolled, the next part is displayed and so on (as can be seen in the attached screen dump).

In short, under these circumstances, Photoshop is completely unuseable.

Any thoughts as to what the problem might be?
