    You could try below M query

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlLSUTIw1zOw1DMyMLQEcoJSE1MqgbRzUWpiSWqKUqxOtJIhkG9ogKTIM08hPL8oG8TKLchJzU3NgykFmWdoQpRSkKkGFsRYbYZsHpIpOkou+XmpcHuBihDqYIYgXIDVJ1iUxQIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, #"Changed Date" = _t, State = _t, Create = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Changed Date", type text}, {"State", type text}, {"Create", type text}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"ID"}, {{"max", each List.Max([Changed Date]), type text}, {"all", each _, type table [ID=number, Changed Date=text, State=text, Create=text]}}),
    #"Expanded all" = Table.ExpandTableColumn(#"Grouped Rows", "all", {"Changed Date", "State", "Create"}, {"all.Changed Date", "all.State", "all.Create"}),
    #"selectrow"=Table.SelectRows(#"Expanded all",each [max]=[all.Changed Date]),
    #"Removed Columns" = Table.RemoveColumns(selectrow,{"all.Changed Date"})
in
    #"Removed Columns"
