Hi @ tjfender,
The error message told that you do not have permission to view this directory or page.
Are you a owner or a member of the sharepoint site?
I have made a test on my side and don't have the issue that you mentioned.
Please check if you are the owner or a member of the sharepoint site to see if you could have permission to the sharepoint site.
In addition,please take a try to create a new site or sharepoint library to see if the issue still exists.
Please let me know if your issue could be solved.
Regards,
Alice Zhang
