Hi everyone,

I'm having an issue with the latest version of Lightroom CC on a MacBook M5 Pro running macOS Tahoe 26.5.1. (I was experiencing the same problem on 26.5 and decided to update hoping it would fix it, but unfortunately it didn't.)

Since this morning, it's been impossible to to use Noise Reduction, even though my internet connection is working perfectly. I've already updated both Lightroom CC and macOS, cleared the cache, and optimized the catalog, but I keep getting this error screen whenever I try to use Noise Reduction.

Has anyone experienced the same issue or knows how to fix it? Any help would be greatly appreciated. Thanks! 🙏

I’m having the same issue. I’ve read a few forums that others are experiencing this issue with the new release, too. https://www.lightroomqueen.com/community/threads/denoise-an-unexpected-error-occurred-while-processing.54952/

When i try to denoise an image it keeps on saying Failed to apply adjustments to the following photos. vAn unexpected error occurred while processing. (1) This is on all the images not just one and on more than one different shoot. This is the first time light-room has sent a pop up like that. Usually when it does not want to denoise is close the app and open it again the it works. Not this time. This is now day 3

Grazie, fortunatamente ieri Adobe ha rilasciato aggiornamento 15.4.1 che ha opportunamente corretto la problematica. Avevo provato ad installare anche la 15.2 ma anche cancellando la cartella CameraRaw il problema persisteva.

grazie molte del riscontro comunque

This popped up suddenly on my MacBook. I upgraded to LR 15.4.1 and it went away.
