Bug? InsertAt in a LIST

'--- the string is created here

    Dim o As StringBuilder
    o.Initialize
  
    o.Append($"g.ToastMessageShowX("Re-Starting Application...",True)"$).Append(CRLF)
    o.Append($"fn.sleep(750)"$).Append(CRLF)
    o.Append($"Activity.Finish"$).Append(CRLF)
    o.Append($"Return"$).Append(CRLF)

'--- this puts it into the list
    Dim lstTmp As List = Regex.Split(CRLF,s)

    Dim lstOfCode As List = lst.Get(1)
    Dim strOfCode As String = lst.Get(0)

Dim lstTmp As List
lstTmp.Initialize
lstTmp.AddAll(Regex.Split(...))
