Get-PWRichProjects ProjectProperties stopped working

We have been using some powershell to return project properties for quite some time already, but it seems to have stopped working.

it is working when when using  PWPS_DAB Version  and 

it is however NOT working on and, and, i even tried updating to the latest

Kind regards Gavin Chapman
