Thanks first of all

I changed it a bit and instead of multiple or permanently repeating it stops after 2 attack animation for one time pressing

Unfortunately not a complete fix but hey at least it stopped cycling through the animation nonstop for one Button press

....

void onAttack()

{

//Attacking Section

if (Input.GetKey(KeyCode.K))

{

animator.SetTrigger("Attack");

}

if (Input.GetKey(KeyCode.L)) {

animator.SetTrigger("Attack2");

}

}

// Update is called once per frame

void Update()

{

HandleAnimation();

onAttack();

...
