Can't create Data Source Object - Class not registered - Error Message

Hi all,

 

I keep getting the below error message - it's happening on around 5 workflows that I was previously able to run with no issues. I get someone else to run the workflow and it works fine for other people on the team - so I can't work out why it doesn't let me when I haven't changed anything.

 

Does anybody have any ideas?
