Strange Rigidbody2D Behavior

Unity Engine
1

In my game prototype, I am trying to make the character throw the sword at the end of the animation.
Everything is okay, till the script gets to actually throwing the sword, instead of being thrown smoothly, it teleports to the position in the image below, and gets stuck, not affected by the ground’s collision or even gravity:

Keep in mind, viewing the sword’s rigid body in the inspector while playing, shows that it’s body type is dynamic.

This is the code inside the function that gets called at the end of the throwing animation.
It’s supposed get the mouse direction, separate the sword from the player, enable the Rigidbody2D’s physics, and apply a force in the calculated mouse direction.

//Get mouse direction
Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector3 mouseDir = mousePos - gameObject.transform.position;
mouseDir.z = 0f;
mouseDir = mouseDir.normalized;

//Get the sword, its rigid body and its collider.
Transform sword = gameObject.transform.Find("WeaponSlot").transform.Find(swordName);

Rigidbody2D swordBody = sword.GetComponent<Rigidbody2D>();
Collider2D swordHitbox = sword.GetComponent<BoxCollider2D>();

//Set parent of the sword to null
sword.parent = null;

//Enable rigid body
swordHitbox.isTrigger = false;
swordBody.bodyType = RigidbodyType2D.Dynamic;

//Apply force
swordBody.AddForce(mouseDir * throwForce);

//Set the states
characterAnimator.SetBool("AimingSword", false);
aimingSword = false;
characterAnimator.SetBool("HoldingSword", false);
holdingSword = false;

Here is the hierarchy of the player’s game object, and its children (RoughSword is the sword I am trying to throw):

The sword’s Rigidbody2D starts off as Kinematic, and it’s BoxCollider2D has “Is Trigger” set to true.

I should say that I just started using Unity, and I apologize if the answer is really basic. I don’t ask on forums, unless I am completely stuck, which in this case I am. Any help is appreciated, thanks!

I have figured out the problem, which is that I am animating the WeaponSlot that contains the RoughSword. The sword is still affected by the animation even when it’s not parented to the WeaponSlot game object.

For anyone in the future that has a similar problem or just curious for my solution:
I instead made a prefab of the RoughSword, and ditched the whole idea of having a WeaponSlot.
I would animate the sword inside the player, but when I get to throwing it, I just disable its sprite renderer and instantiate a sword prefab with the same position, rotation etc, and apply the force to it’s rigid body instead. This works fairly well for what I am trying to achieve.
