completely locked out of the department database error 0x80070005

Hey team,

I'm locked out of our department's main archive database and completely blocked from accessing any client records for the audit tomorrow. Every time i submit my login credentials, the screen immediately sends the message "Critical Error: Access Denied - Security Descriptor Mismatch (0x80070005)" . I already tried restarting the host machine and reinstalling the local management software, but it fails with the exact same error every single time.

Kindly please do the needful as soon as possible to restore my access. Thanks
