i fix this issue by updating System.Net.Http.Json(in app project) and System.Text.Encodings.Web(in android project) and System.Text.Json(in windows project) to the latest version(6.0.0) and subsequently build the solution.

public static DataTable ConvertToDataTable(this XmlElement data) { StringReader theReader = new StringReader(data.InnerXml); DataSet theDataSet = new DataSet(); theDataSet.ReadXml(theReader); return theDataSet.Tables[0]; }
