Godot, помогите с кодом

Question

из-за этого кода у меня перестали функционировать кнопки, что делать ( могу дать весь код или прикрепить скрины)
func _on_shop_pressed() -> void: 
	 
	if not is_shop_visible: 
		_shop_instance = shopin.instantiate() 
		get_tree().get_root().add_child(_shop_instance) 
		_animation_player = _shop_instance.get_node(&#34;AnimationPlayer&#34;) 
		_animation_player.play(&#34;SlideIn&#34;) 
		is_shop_visible = true 
	else: 
		_animation_player.stop()  # Stop the first animation 
		get_tree().get_root().remove_child(_shop_instance) 
		_shop_instance = shopout.instantiate() 
		get_tree().get_root().add_child(_shop_instance) 
		_animation_player = _shop_instance.get_node(&#34;AnimationPlayer&#34;) 
		_animation_player.play(&#34;shopout&#34;) 
		is_shop_visible = false 
	$store.play()

extends Node2D 
 
export var shop_scene = preload(&#34;res://scenes/Shop.tscn&#34;)  # The shop scene  
var shop_instance = null 
var is_shop_visible = false 
 
func _on_shop_pressed(): 
    if not is_shop_visible: 
        if shop_instance == null: 
            shop_instance = shop_scene.instantiate() 
            get_tree().get_root().add_child(shop_instance) 
            shop_instance.get_node(&#34;AnimationPlayer&#34;).play(&#34;SlideIn&#34;) 
        else: 
            shop_instance.get_node(&#34;AnimationPlayer&#34;).play(&#34;SlideIn&#34;) 
        is_shop_visible = true 
    else: 
        shop_instance.get_node(&#34;AnimationPlayer&#34;).play(&#34;SlideOut&#34;) 
        is_shop_visible = false
