Photoshop 2023 Program Error using Brightness/Contrast
Unfortunately, the subject says it all.
If I try to access Brightness/Contrast for a layer, I get "Could not complete the Brightness/Contrast command because of a program error" and can go no further.
I can use Hue/Saturation, Exposure, Levels, Curves, Vibrance ... but not Brightness/Contrast, which I use about a thousand times every day.
I have replaced the installation with older versions of Photoshop, such as the one I used only yesterday, but with the same problem.
Can someone please help or advise? I am on MacOS (latest version) on a Macbook Air M1, and with the very latest version of Photoshop 2023 (not that it makes a difference: the update seems to have messed up all previous versions as well).
