Urgent Assistance Required: User Able to View Own Data

We are facing a critical issue where users can view their own data, despite implementing the necessary restrictions in the Person Security Profile.

We have ensured the "View Own Data" checkbox in the Person Security Profile is unchecked.
The roles, privileges, and data security policies have been thoroughly reviewed and verified.
We are using a custom SQL query (attached) to restrict data visibility.Despite all attempts, the restriction is not working, and admins are still able to view their own data.

Steps Taken:

1.we have verified Person Security Profile configuration.

2.Checked all roles, privileges, and associated data security policies.

1. Tested custom SQL with alternate conditions (piece of code also attempted but failed).
