User security: error occurs as soon as a user starts Vantage with hi

We are on Vantage 8.408b.

A user suddenly experiences a problem when he starts running Vantage. The user has not experienced such problem before.

Specifically, as soon as the user launches Vantage with his own login ID, error message as below occurs. However, the problem does not happen when the user is switched from another user (using 'change user ID'). The system behaves normal and not getting any error message when the user launches Vantage upon switching the login from another user login.

I would appreciate if someone can provide pointers or even possible solution to this problem that we now have.
