Older DNG files are coming up green but work in LRC

I have an older set of images from an older camera that created raw images in a CRW format. I found that Lightroom Classic didn’t like the CRW format and therefore I converted the images to DNG using Adobe DNG Converter such that LRC now likes and has no issues. The problem arises when I export a copy of the DNG to Topaz Photo AI and the images appear completely green. When saving the image and importing back to LRC in the process, the imaged are still green shifted such that they are unusable. I have tried this with multiple versions of Topaz including 2.3.2. 100% of the images I try come out this way so I suspect that Topaz AI doesn’t have full support for this specific raw format even though LRC does.

Log shows this warning:

[2024-02-26 12:54:31.397, 885.70 μs] [3c54] Warn | ICC Profile description not found, defaulting to sRGB.

Steps to reproduce issue:

  1. Import DNG to LRC. Normal color profile.

  1. Export to Photo AI via plugin method or open dng directly from Photo AI menus.
  2. Image appears massively green shifted.

  1. Saved processed dng is now seen to LRC as green also.
    (same appearance as above so you can imagine).

I’m happy to send or attach a sample DNG for you to examine the headers.
