The error message is indicating that rightHand isn’t set, which is odd since you’re showing images of an inspector where they are set… Is it possible you have more than one enemy?

One of the tricky parts about Error messages is that they tell you the script, but not the object… Let’s see if we can narrow this down.
Let’s add a Debug statement to the first line in DestroyOldWeapon:

if(!righthand)
{
    Debug.Log($"{name} has no right hand transform.");
    return;
}

This will show which item is missing a transform.
