The result is that I can only open the project in read-only mode. The way I resolve this is, I login to platform.uipath.com, delete my robot. Restart UiPath Studio. Back to orchestrator, create new robot and everything is fine.
But surely this is not the way it is meant to be. Right? I mean, I should be able to open a project in Studio, in write mode, even when UiRobot is running, right?
