Topaz Sharpen AI does not open

I’ve had a problem for a few days with TOPAZ SHARPEN AL, the program doesn’t open anymore, the other 2 programs I have (TOPAZ DENOISE and TOPAZ GIGAPIXEL) work fine. I have an iMAC Retina 4k, 21.5-inch, 2017

Exact same problem here… the program opens but displays no interface

Have contacted support but not heard back

Do support look at this forum? I cannot get anything from them

Mine is not opening either. I uninstalled and installed it and nothing.

I have the same problem, has anyone solved it?
