Transaction form "Access control" affects admin access

If Access control (in any transaction form) is by role, and a role other than Administrator is selected, then an administrator is unable to assign the form path to a menu link. (Any attempt to use the path in a menu link results in the error "The path 'transact/form_name' is either invalid or you do not have access to it".)

The workaround is to set form Access control to role = Administrator, then create the menu link. After that, Access control can be set to any other role and the menu link will work correctly.
