The error message is very clear, you have a permission error. Without knowing a lot about your environment is is not possible to be of more help. If it is your PC then only you can fix, if it is work or school see your admin.
Great news: Your security settings are working as intended and protecting your files. Simply put, you don’t have administrator privileges and therefore don’t have permission to access certain files or folders on your system, including this one.
To resolve this, you’ll need to adjust the permissions to grant yourself access. If this isn’t your computer, you’ll need to ask the administrator to make the necessary changes for you.
