func go_to_checkpoint() -> void:
$knight_hitbox/CollisionShape2D.disabled = false
checkpoint_tween.interpolate_property(self, "position", position, last_checkpoint.position, 0.4, Tween.TRANS_EXPO, Tween.EASE_OUT)
checkpoint_tween.start()
$ded.start()

it just don’t work
it is code for checkpoint

Tween node has been removed from godot 4.x editor they are no longer nodes
so you have to add them manually in the code

see the documentation
