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! 🙏

After updating to LrC V15.4.1 Denoise still fails with this message:

I suspect the error is caused by custom camera profiles that, after a clean install, were added to the macOS folder '/Users/addieleman/Library/Application Support/Adobe/CameraRaw/CameraProfiles'.

Immediately after the clean install Denoise did not fail.

Anyway, everything is reverted now back to LrC V15.3.1 including the manual install of Camera Raw 18.3.
