Workflow Designer encountered problems with your document - GetQueueItem and SetTransactionStatus

Hi, I’m trying to opening and work with a workflow and I get the following errormessages:

All packages installed and up to date. Also when I’m trying to delete the “Activity cannot be loaded because of errors in the XAML” and drag a new activity in I get following:

Can someone please suggest a solution for this. When my colleague is working with the workflow it works fine and we are on the same uipath studio version (2017.1).

I’ve search around here in the community, but can’t find a solution.
Any suggestions?

Thanks and regards

Were you able to resolve this ? I am getting the same error for studio version 2017.1
