A. The Users defined in the advanced policy do not include the end user running the application.
The error could be caused by the fact that the end user's account is not included in the list of users defined within the advanced elevate policy. This means that the application is elevated for the specified users in the policy, but not for the specific end user who is experiencing the issue. As a result, when the end user tries to access the certain menu item that requires administrative rights, the application crashes since the necessary elevation is not being applied to their account.
To resolve this issue, the end user's account should be added to the list of users defined in the advanced elevate policy to ensure that the application functions properly when that user interacts with the menu item.
