Which member of the Queen's family stepped down as a full-time working Royal?

The choice of Prince Harry as the member of the Queen's family who stepped down as a full-time working Royal is accurate. In early 2020, Prince Harry and his wife, Meghan Markle, announced their decision to step back from their roles as senior members of the royal family. This move was highly publicized and marked a significant shift in their lives as they sought financial independence and a new path away from royal duties.

Prince Harry's decision was rooted in a desire for personal freedom as well as concerns for the well-being of his family, particularly amid the intense media scrutiny they faced. Following their departure, Prince Harry has taken on various philanthropic endeavors, focusing on mental health and environmental issues, among others.

The other royal family members listed did not take a similar step to relinquish their full-time royal responsibilities. Prince William remains actively involved in royal duties alongside his role as a father and is second in line to the throne. Prince Andrew faced his own controversies but continues to be associated with royal events, while Princess Eugenie, while not a full-time working Royal, has not made headlines for stepping down in the way that Prince Harry has.
