DeNoise AI V2.3.6 not working

The initial versions of DeNoise AI worked brilliantly but… installed the lates update and ever since then … problems. Installed on macOS Catalina 10.15.7 and used as a plugin with Lightroom Classic (LrC ver 10.1). The AI preview is no different to my original image and despite my trialling the sliders up to 100%.
I posted yesterday but with no response to my issue . I have spent good money on Topaz products. Very disappointed at this moment in time.
Please respond with a fix.

Don’t post in more than 1 place, its already in the v2.3.6 thread. If you want technical support from Topaz raise a support request at the main website.
