Can you supply an original raw file before running Denoise?

Thank you for the reply. How could I upload a raw file?

You'll need to use something like Dropbox (free) to upload a raw for others to download.

I can replicate the failure with your file. I will log a bug with the Camera Raw Team.

Interresting, its the same effect as with Fujifilm RAF files. I reported this P: X-T2 Fuji Files have small purple artifact at edge of image after Denoise also in June but until now there was no fix reported.
