error: not a correct XFS inode after WHM Update Reboot

Today after seeing the update notification in WHM I performed the usual graceful reboot (after clicking the notification etc.), and I noticed the server wouldn't come back online. I couldn't SSH or connect in any way. Since I host WHM on Google Cloud, I could check the serial console output on the instance, and I noticed the following Error showing up repeatedly: error: not a correct XFS inode I have tried to open a cPanel support ticket yet my login credentials are not accepted and have not received an email to reset my password. What do I do?
