It is normal for freshly baked cookies to be soft and crisp when they cool. If they are still soft after cooling, it means that the baking time was not enough and the moisture was not completely dried out. The solution is to put the cookies back in the oven for a few minutes. If the cookies are dark enough but still soft when cooled, the oven temperature may be too high. At this point, try lowering the oven temperature and baking the cookies longer. Also, the larger and thicker the dough, the harder it is to dry out the moisture and the easier it is to bake soft cookies. Conversely, the smaller and thinner the dough, the easier it is to bake crispy cookies. So, if you've been unable to bake cookies with a satisfying texture, try making them smaller
