Thanks for sending this information. This is a known issue with the NVIDIA RTX AX000 series graphics cards.
We are working on a fix. For now, open Topaz Photo AI and go to the Edit > Preferences > AI Processor menu. In the dropdown menu, select the Intel UHD graphics card for processing.
Thank you very much for the suggestion. After changing the AI Processor to the (slower) Intel UHD graphics card, I was able to preview, process, and save the sample image.
Process some images and let me know what happens. If you see any errors or issues, open Topaz Photo AI, go to the menu bar on the top and click the Help > Open Log Folder menu option. Email me all the logs files that you can see in the window that opens.
