Game freezes if I dont move after entering an area

So im new to Godot and trying to make a basic enemy. I'm trying to give it a wandering and chase state by making an area2d and using on_alert_body_entered/exited to change between the two states. That works just fine, however after a few moments or if I stop moving while in the area of the enemy, the game freezes. the movement code for both the player and enemy works perfectly fine, and if i remove the on body enter i have zero issues. also, if i never enter the enemy area, it also works fine
Heres a video showing this, if you need a visual:

i am completely stumped as to what im doing wrong. please help

i am using godot 4.0 on windows, if that's relevant

code(i don't know how to format this help):
`
extends CharacterBody2D

@onready var sprite=$AnimatedSprite2D
const movespeed = 100
const chasespeed = 200
var gravity = ProjectSettings.get_setting("physics/2d/default_gravity")
var state = "Wander"
var direction = 0 
var HP = 3
# Called when the node enters the scene tree for the first time.
func _ready():
	
	while true:
		if state=="Wander":
			await get_tree().create_timer(2).timeout
			direction= randi_range(-1, 1)


# Called every frame. 'delta' is the elapsed time since the previous frame.
func _process(_delta):
	if velocity.x > 0:
		sprite.flip_h = true
	elif velocity.x < 0:
		sprite.flip_h = false
	if HP<=0:
		queue_free()
	if state == "Wander":
		print("Wander")
	elif state == "Chase":
		print("Chase")
	
	
	
func _physics_process(delta):
	velocity.y += gravity * delta #gravity
	if state=="Wander":
		velocity.x = direction * movespeed
	
	if state == "Chase":
		velocity.x = direction * movespeed
	move_and_slide()



func _on_alert_body_entered(body):
	if body.name=="CharacterBody2D":
		state="Chase"

func _on_alert_body_exited(body):
	if body.name=="CharacterBody2D":
		state="Wander"
