What reasons do Catholic scholars or the Catholic Church cite for rejecting the story of Pope Joan as historical fact?

The story of Pope Joan—a woman who allegedly disguised herself as a man and became pope in the Middle Ages—has circulated in various forms for centuries. However, I understand that the Catholic Church considers this story to be a legend rather than a historical event. What specific reasons do Catholic historians, theologians, or official Church sources give for rejecting the claim that a female pope ever existed? Are there particular historical inconsistencies, lack of documentation, or theological arguments that lead them to conclude the account is fabricated? I'm particularly interested in answers that reflect the Catholic perspective, supported by historical or doctrinal sources.
