Read-only problem with the latest version of studio

hi guys, i have a project which was created with Studio 2019, and now when i open it with the latest studio version (2021) with the community license i have an error message in the startup "Detected Attended Robot as the license type. Based on the terms and conditions, this license should only be used for running and debugging purposes. Editing is restricted "(see image below), and most workflows are read-only, note although the project was developed with studio 2019 containing the corporate license. thanks guys for your help.

It is regarding the robot type on the orchestrator.

Change or add a new robot with unattended or developer type and connect same with your machine.

i am new to this. As I was practicing . Then I exit. then I deleted all the files so I can redo it . then its showing same thing. "Detected Attended Robot as the license type. Based on the terms and conditions, this license should only be used for running and debugging purposes. Editing is restricted ". most things are read only now.
(Studio 2021.4.3 - 5/7/2021
