Forensic and statistical analysis FAILED the exam

I took MLS-C01 exam at 2023 1st March use OnVue platform at home, However today I received this email from AWS that I failed when they performed some forensic analysis next day. I didn't do anything. I showed invigilator everything I was doing and he had no objection. I didn't speak or used any program other than OnVue secure browser. And now I receive this email. It also says all my previous certifications are revoked. This is a system generated email and I cannot reply to it. Who am I supposed to contact here I'm literally shaking right now. The whole exam worked smoothly, I spent a lot of time to prepare this exam, I can't believe that happened, so Frustrating !!!! If that I have to leave AWS, do not touch it anymore!!!
