Error installing datasmith plugin for twinmotion

hello I get this error when trying to open rhino after installing datasmith plugin.
I’ve already tried to unistall and reinstall datasmith plugin I even tried to remove leftover registry entry for datasmith but nothing worked.
The Twinmotion installation looks finished properly but when I open rhino nothing works. Anyone got the same errro?

I too got this error and gave up in the end….would be interested to hear of a solution
