SketchFX keep crashing SU

It was working fine.
Today it crashed the program every time I tried to use it.
I downloaded a new copy, uninstalled the extension, and loaded the new copy.
I still crashed.
It’s SU 2020 on a Mac OS Catalina 10.15.4
Please help!

Hi Robert,
Please download the latest SketchFX version from the user panel (clicking the “manage licenses” link in the purchase confirmation email). If you’ve installed AmbientOcclusion, please make sure you’ve installed the latest version or delete it.
