Leica Q2 Monochrom weirdness via "Process with Topaz Photo AI" in Capture One 23

When i open a Leica Q2 Monochrom DNG via “Process with Topaz Photo AI” in Capture One 23 and use DNG, the file is all messed up when Photo AI opens.
When I open the DNG straight from Photo AI it renders correctly.

I believe this issue may be due to the DNG file that Capture One creates. I can verify and share this with my team once I have the file.

Hi Lingyu

I’ve just uploaded the requested files.

It’s important to note that Capture One crashes once I complete the round trip.
After reopening Capture One again and trying to sync the folder to show up the DNG that was saved by Photo AI, it crashes again.

Thanks for uploading the files. I just tested and was able to reproduce the issue. It looks like the output DNG from Topaz Photo AI is invalid.

I created a task for my team so we can look into fixing this. I will bring it up at our meeting tomorrow.
