Urgent Assistance Required: AWS Server Boot Issue, FortiClient Installed in this server

[PMukeshKumar1991]

I am reaching out to request immediate assistance with an urgent issue we are encountering on one of our AWS instances. we stopped the server and restarted the server for maintenance purposes, it is stuck on the boot screen and does not proceed further.

The system is displaying the message:
"System is starting...
Serial number is FGUMSLTM20004409

This is a private computer system. Unauthorized access or use is prohibited and subject to prosecution and/or disciplinary action...
