Workflow Designer window NullReferenceException error when connecting UiPath Robot with Orchestrator

Dear all,

as per screenshot in attachment, I get a “NullReferenceException” error message every time I open any UiPath Studio while UiRobot is connected to Orchestrator.

To be clearer, by “UiRobot is connected to Orchestrator” I mean that the UiRobot icon in the desktop taskbar is on and in its settings I connect Orchestrator by providing Machine Name, Robot Key and Orchestrator URL.

When I disconnect, this error message disappears. What can it be?

Many thanks

Kind regards

Hello there,
This a known issue.
Will be fixed in coming release.

PS: You can also avoid this by not using double click on the xaml file to start it, and Open it from Studio
