Where can i choose an active robot in studio

I’m studing 3 Level of RPA development and have a question.
i had a registred robot in Orchestrator with name “MyRobot”, then i deleted this robot from Orchestrator and created another with name “TestRobot” and reconnect my PC to it.
But now i have a problem: When i’m trying to run any project in studio it writes me an error message: uipath robot with username MyRobot is not defined in orchestrator.
Where i can change robot name in Studio? I dont what to create MyRobot again. I want to use a robot with another name. I tried to restart PC and reconnect robot to Orchestrator - all the same.
The only one way to run project is to disconnect robot from Orchestrator, but this is very poor solution…
