Topaz 2.2.2 PhotoAI denoise function is generating rainbow artifact

Topaz 2.2.2 PhotoAI denoise function is generating rainbow artifact. This photo was shot at ISO 2200 and had a little noise but denoise was initially turned off. When I turned it on I see the artifacts. This is a picture of a bird and has a lot of fine feather detail.

John, I’ve uploaded the .NEF file, the .TIF, and a screenshot of the PhotoAI denoise settings. Let me know if you need anything else. I don’t think I mentioned this earlier but I’m working from Lightroom and using the Edit In > Topaz Photo AI function.

Thanks for sending in those images. I was not able to reproduce these artifacts you were reporting, however I was making these edits with the most recent update.

To troubleshoot this issue I would like to try updating you to the most recent version release to see if this resolves the issue.

Please make sure you’ve also turned off any firewall, VPN, or proxy that may be on your computer. These are known to block the installation. Also, make sure there are no settings or configurations in your OS system that could interfere.

Try using the appropriate OS system link to update:

I reinstalled using your link. I’m still seeing the same result. Note that the Autopilot did not identify the image as needing denoise - only sharpening. The rainbow effect only shows up when I turn Denoise on with the toggle switch.
