Insert this as your next step where Source must be replaced with your previous step

= Table.Combine(List.RemoveNulls(List.Transform(Table.Group(Source, {"ID"}, {{"All", each _}})[All], (x)=> if List.Contains(x[Status], "Closed") then null else x)))

 Complete code for testing

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjZR0lFyTC7JLEtVitUB8i2A/AAEE0nKBKQ0MSk5BcFzzskvToXyTYF8j9ScnHww19QAZE5qXkpmXjpCAKY+FgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Status = _t]),
    #"Grouped Rows" = Table.Combine(List.RemoveNulls(List.Transform(Table.Group(Source, {"ID"}, {{"All", each _}})[All], (x)=> if List.Contains(x[Status], "Closed") then null else x)))
in
    #"Grouped Rows"
