TOAD for Oracle 12.6.0.53 -Package Body does not exist or you do not have the necessary privilege to access it

I am a new user of Toad.

I created a package then was able to compile and run it.

When it came to trying some changes, these changes were not saved successfully.

Next I deleted the package and tried to create a new package and I got the Warning"

“Package Body does not exist or you do not have the necessary privilege to access it”

If this is a privilege issue?

Any help will be appreciated. Let me know if I need to give more information.
