Square Grid/Line Artifacts on RAW noise removal in Photo AI

I’m getting these square grid shapes/artifacts when running RAW noise removal from file > plug-in extras > process with topaz labs photo AI in Lightroom Classic. See attached screenshot of what I mean - particularly in the sky however I’ve seen it happen all throughout the photo. It’s worse in low light shots.

Photo AI Version: 3.3.3 (log file is attached)

Attached system report from my Macbook Pro as well.

The only workaround I’ve found is to not use RAW noise removal, and instead to use the regular denoise enchantment after removing raw noise.

Is there a fix for this?

Steps to reproduce issue:

  1. In lightroom classic go to file > plug-in extras > process with topaz labs photo AI
  2. Photo opens in photo AI, applies RAW noise removal automatically
  3. Export back to lightroom classic as a dng. The square patterns and line artifacts are present on the dng.
