When you arrive at the escape point while using the jetpack, the jetpack flies in the direction you were moving.
Under the same conditions, when a zombie uses a special “grab” attack, there are times when Annie can’t get passing the zombie because the ignore collider is not activated, and that’s when the jetpack seems to fly away with Annie’s collider and trigger in the direction it was moving last.
In this case, Annie seems not wearing a jetpack, but she can use the function of the jetpack, and if the jetpack that flew out of sight is attacked by the enemy, she can move normally, but an escape gauge appears like a grab situation and after few second becomes a game over.
