I have the latest version of Photoshop running on an iMac with MacOS Ventura 13.5.2. I install Photo AI 2.0 it will not open up using: File > Automate > Topaz Photo A. All it does is add a TPAI layer but will not bring up the app to make any adjustments. I have installed and re-installed Photo AI 2.0 and got the same results.
Thanks for reaching out. How much system memory do you have on this computer? You can check from the Apple > System Information menu.
Please open Topaz Photo AI, go to the menu bar on the top and click the Help > Open Log Folder menu option. Attach the Automate Filter Log.txt to your reply here and I can check what is happening.
