This is a bug in certain, older versions of DeNoise AI for Windows in which DeNoise AI inadvertently installs a Beta plugin that does not function. To remove the Filter from Photoshop, follow these instructions:
Navigate to the DeNoise AI plugin directory (Default C:\Program Files\Topaz Labs LLC\Topaz DeNoise AI\PS_Plugins_x64)
Delete the file named tltopazdenoiseaibetaps_x64.8bf as it will crash Photoshop if you aren't using the beta version of the program.
- Restart Photoshop and the errant Beta filter should be removed.
