Using the term "female" to describe a woman can be perceived as reductive and dehumanizing because it reduces her to a biological category. By using the term "woman," the focus is shifted from her biological characteristics to her identity as a person, which is a more respectful and accurate way of addressing her.
Worth noting is that there is no equivalent term to "female" when referring to men, who are almost always referred to as "men." This is because there is an underlying cultural assumption that men are the default and women are the exception. While the use of the word "female" to describe a woman is not inherently wrong, using the term "woman" is more accurate and respectful, and nobody would use the term "male" to describe a man in the same way.
