Recently updated Lightroom classic to 15.3.1 on a Macbook Pro. Denoise returns "an unexpected error occurred while processing. (1). Same problem with raw files from Sony A7iv, A7v and A7cr.

Lightroom Classic version 15.3.1 on a Macbook Pro running macOS Tahoe 26.5.1

When I select Denoise, an error is returned immediately “an unexpected error occurred while processing. (1).

Same problem with raw files from Sony A7iv, A7v, A7cr.

Files have not had any processing done prior to this step.

Tried restarting my Mac and also restarting Lightroom. No Change.
