Hey @david_tattersall 
Welcome to the Postman community! 
It’s difficult to see what’s happening from that information 
Are you able to share an image of the full app window including the request that is showing that error.
Most likely, you have unsaved changes in the request. If a change has been made to a request tab in between a collection run and not saved, that wouldn’t be picked up by the runner.
