Check this documentation Frequently Encountered Robot Errors
After you logout from the Windows 10 machine from all users, you don’t need to be logged in with any users (they will use the Console sessions).
You need to schedule the job from another computer or mobile device that has access to your Orchestrator.
Also, it looks like the account you are using for the Robot is locked out (may be due to too many unsuccessful login attempts). To make sure this is the issue try logging into the Machine using the same credentials manually & if you see account locked message then unlock the account → it should work.
