Upverter error when using fork. Upverter crashed on forked design


Using fork Upverter reported an error during the fork.
Upverter crashed on the forked design. Endlessly trying to open the design and crashing.
I’ve had other designs that reported errors during forking.
I was always to open these new designs.
Except this time?
What could be the problem?
Upverter reports error on server. " The tool experienced an error" right during "establishing a connection.
Thank you
