Так если есть десериализация, то откуда взялся Rank r = new Rank(); ?

using (var reader = XmlReader.Create("Garena_RankUp.xml"))
{
    var serializer = new XmlSerializer(typeof(List<Rank>), new XmlRootAttribute("RankUpData"));
 
    try
    {
        var ranks = (List<Rank>)serializer.Deserialize(reader);
 
        foreach (var rank in ranks)
        {
            log.Debug($"#{rank.Id} {rank.Title} {rank.RequiredExp} exp");
        }
    }
    catch (Exception ex)
    {
        log.Error(ex);
    }
}
