Problem faced during SAP Backend Developer ABAP Cloud Beta Version Certification Exam

Dear SAP Team, I am writing to urgently request technical assistance with my SAP ABAP Developer Assessment exam, which I scheduled and launched today at 4:30 PM (IST). My exam timer of 3 hours has started and is currently running, but I am completely locked out and unable to access the examination environment due to authentication errors on your end. Following the provided instruction PDF, I clicked on the “Access System” link.
