Denoise AI purple/blue tint

fehler in lightroom classic 14.5.1 mit  camera raw 17.5: beim entrauschen der row-bilder bekommen die fotos einen starken violetten farbstich

I'm having the same problem but I don't understand why because it was working just fine yesterday

hello, this is my first thread here, hope to get some help to solve my problem. When using AI noise reduction on LRC on my Pc all the resulting images are systematically blue tinted. This kinde of issue doesn't happend whit the same images on my travel macbook air.
I've tryed to uninstall and install again LRC but notthing chaned.
Any clue?

Hi,

Using Denoise results in a purple hue being applied to my image.

I tried updating my GPU driver (AMD Radeon RX 6600M/ AMD Radeon(tm) Graphics) but the system advises I already have the latest drivers.

Below is the System Info from Lightroom

---------------------------------------------------------------------

Hi, I just moved to a new PC and immediately ran into a problem with the Enhance function. When I apply the enhance denoise, I get a purple shift as seen on the attached photo. (right is the "enhanced" photo.This is for NEF files from a nikon Z6. All photos I've tried have the same purple shift with the denoise function.

I've just installed lightroom and applied all the updates so I should have the latest drivers/versions.In my initial investigation, I set the display preferences to sRGB and also turned off GPU acceleration. No luck

I used the enhance function on my old PC and it worked well.  What is going on and how can I fix it?

Hi, I recently installed Lightroom Classic , previously I always used Lightroom 6.
In the first tests when I apply noise reduction, with factor 40, the dng created has a purplish dominant on the whole image. This also in Photoshop camera raw. I can't understand why... where I'm wrong. Thanks in advance.

I am also having this issue. The first handful of times I used the Denoise feature thigns worked fine. Then all of a sudden it stopped working and turned my images purple.

I'm having the same problem, but updating the GPU driver failed to fix the issue. Windows 10, Ryzen 5800, XFX RX 6700 XT GPU, 64 GB RAM.  The really annoying thing is that it won't let me undo the denoise so I can just use the old adjustments.
