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 now receive an error message when I want to denoise an image.
Message says “An unexpected error occurred while processing. (1)”

After upgrading to LRC 15.3.1 Denoise stopped working. I have a MacBook Air M4 MacOS 26.5.1. I tried reseting my preferences and turning off GPU acceleration. LRC catalog is local and the images are on external drive. I have tried moving images to local drive still not working. I have 65 GB free space on my local HD and 24 GB ram

It's the same for me. Just did the upgrade on the programs that had new versions in Creative Cloud, and just completely lost the denoise function in Lightroom Classic. I´m not interested in any special solutions like searching in folders and so on. I just want to know if there will be a quick update from Adobe addressing the issue. Seems there are more people than me having this issue...

When Lightroom Classic 15.4 is once again available, that problem should be fixed.

Well, when is that supposed to happen? I’m kind of stuck right now with my current work. Huge oversight from adobe to update camera raw that breaks older versions of lightroom and not have the current version available for everyone. I’ve seen some people are on 15.4 but its not available for me.
