When it came out, did it pop off (broken part) or slide out smoothly (mechanism malfunction)?
By the look of it, the issue is not with the crown or stem, so I would guess either the locking mechanism was not correctly assembled and therefor malfunctioned (somewhat unlikely) or more probably the locking screw was loosened / stripped and therefor malfunctioned (ROs are somewhat notorious for having crown issues if even slightly overwound).
