Photoshop cannot use input ICC profiles (scanner and camera)
Issue: Photoshop can't Assign 'input' type ICC profiles - profiles which have worked fine with earlier PS versions
Adobe Photoshop Version: 25.2.0 20231121.r.196 12a6c2a arm64
macOS Ventura 13.5
open an RGB image
Go to edit / Assign profile
choose a scanner profile
Photoshop gives an error: "Could not complete the Assign Profile command because the ICC profile is invalid.”
Expected result: Photoshop should Assign the ICC profile to the frontmost image
Actual result: Photoshop refuses with an error message
Profiles I tested have LAB PCS
I can provide an example to test but cannot upload an ICC profile via this interface it seems (unsupported filetype)
I hope this helps
