Looks like a 1st stage fan failure. Wonder if they had a bird strike? however, never seen one this bad before, where the entire hub, shaft and containment case are destroyed.

Bypass fans have a single stage. So I guess "1st stage fan" is technically correct. 😏 There's been a spate of disintegrating fan disks the past couple of years.
