Topaz Photo AI SLOW/HANG!

Topaz Photo AI 2.3.2 suddenly became very slow (it worked fine for a while). Slow for open image and even when trying to open the Preference. The performance is so slow that it almost seems not responsive. Opening the preference took a few mins.
I did try restarting the Photo AI and rebooting my computer and it didn’t help.
I upgraded to AI 2.4 and had the same issue. I tried changing the AI Processor from Auto to CPU, M1Pro and it didn’t help.

Tested the following:

  1. Before upgrading to 2.3.2, it was working fine
  2. Upgraded to 2.3.2, it worked for the first few images and suddenly became slow
  3. Upgraded to 2.4 and had the same performance issue
  4. Removed 2.4 and reinstalled 2.3.2. It worked for the first few images and suddenly became slow

Topaz Photo AI [v1 2.3.2] on [Mac OS Sonoma 14.1.1. Chip Apple M1 Pro, Memory 16 GB]

This problem was resolved by deleting the plist files Topaz Photo AI Freezes on Importing Image (Mac) - Topaz Labs
