Environment

Product Version: 9.10

Resolution

This issue could be a result of changing the VSD version used. Changing between, for example, the Linux VSD version and the MacOS version or if there is an issue with the working files that VSD creates while running. VSD creates the following 3 files in the $HOME directory:
 

1. .vsdrc
2. .vsdconfig
3. .vsdtemplates

If these files do not exist when VSD is launched then VSD will create new files. To resolve the issue, the three .vsd* files can simply be deleted. Afterwards, VSD will launch correctly again.
