Welcome to the UIpath Community.

Are you trying to running this workflow from Orchestrator or UIpath studio ?

from Orchestrator

@Shruti_Gupta

Ok. Is the system connected to Orchestrator or not ?

Could you please show me the screenshots of Robots and machines page orchestrator and also Robot system tray page. Will check it once.
