I want to inform you all that i am aware of the Google Drive issues which you are seeing on some files and i am trying my best to fix it. It seems like something is getting either tested or change on the google side which is resulting into the error in creation a copy or backup of starred file.
I know that some of you are facing issues in copying files and during copy they see error on the starred file. In this situation i want to request you all to be relax and wait for few hours as this require some testing. Its most probably on the services side of google so a wait for a day or few hours is required.
