Hi ​@Saravanavel !

Thank you! 

Today same thing happened to me I start the exam, whole screen turned white and got a message that detected suspicious activity,  without even doing anything and now, no start button is appearing and getting same error as @Saravanavel, that really weird and frustrating.

I have raised issue please help me to resolve it as soon as possible because I have deadline to complete the certification.
