Unrecoverable error when using New SVGA button in Text and 3D Shape plug in

I have been loading in SVGA files with the Text and 3D shape plugin regularly, with no problem. Using ZB. 2018 and windows 10.

But out of the blue I now get an Unrecoverable error message when I press the New SVGA button?

Nothing has changed with my system since this started happening

I even upgraded to ZB 2019 but still same problem.

Any body have any ideas on what might be causing this?

Thanks.
