P: AI Denoise producing purple streak on the edge of the image in latest version

When I use the AI denoise feature a very distracting purple streak/band appears on the lower edge of the image (see screenshots). I expect Camera Raw to not produce a purple streak on the onage after using AI denoise. I was looking back at some files with AI denoise that I created with earlier versions of camera raw and I do not see this happening. The original file of which the screenshots have been taken after adding denoise AI is available here.

I´m using the AI denoise feature in the latest version of camera raw (17.4.1) , same happens in Lightroom Classic in the latest version (14.4). MacOs version is Sequoia 15.5 (24F74). The camera used to shoot the attached dng  is a Leica SL2.

Many thanks for your quick help/action on this!
