Every time I try to add an Auto UV node it quickly crashes and shows these messages for a split second and then they go away and the application closes.
In this image I attempted to place the Auto UV node above the Substance. I tried it after removing the Substance node as well to see if it would make a difference, but it did not.

It happens in 18.348, 352,353, and 355. Each with their corresponding version of SideFX Tools.
I can place it as long as a node under it is not activated, but any time it becomes active it crashes out.
Thanks,
