How to remove CharacterBody2D from the scene after playing an animation? (Godot 2D)

I'm trying to make a character be removed from the scene after playing an animation. Do you have any ideas how this can be done? After the player enters the ‘DeathDetector’ (Area 2D), the animation plays indefinitely.

 extends CharacterBody2D

var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
var alive = true
var chase = false
var speed = 100
@onready var anim = $AnimatedSprite2D

func _physics_process(delta):
    if not is_on_floor():
        velocity.y += gravity * delta
    var player = $"../../Player"
    var direction = (player.position - self.position).normalized()
    if alive == true:
        if chase == true:
            velocity.x = direction.x * speed
            anim.play("run")
        else:
            velocity.x = 0
            anim.play("idle")
        if direction.x < 0:
            anim.flip_h = true
        else:
            anim.flip_h = false
        
    move_and_slide()



func _on_knight_detector_body_entered(body):
    if body.name == "Player":
        chase = true



func _on_knight_detector_body_exited(body):
    if body.name == "Player":
        chase = false



func _on_death_detector_body_entered(body):
    if body.name == "Player":
        body.velocity.y -= 50
        death()

func death ():
    alive = false
    anim.play("death")
    await anim.animation_finished
    queue_free()

The animation_finished signal will never be emitted if the "death" animation is loopable; this prevents queue_free() from executing.

To fix this, select your AnimatedSprite2D node, open the SpriteFrames panel at the bottom, choose the "death" animation, and toggle off its loop property.
