VBA打开工作簿，退出代码

我尝试使用

Private Function readFiles(ByVal lv_path As String, ByRef lx_wrkShDes As Worksheet)
    'On Error GoTo ErrorHandling
    Dim lx_objectExcel As New Excel.Application
    Dim lx_wrkBkSrc As Workbook
    Dim lx_wrkShSrc As Worksheet
    Dim lx_shrPathObj As Object
    Dim lv_shrPath As String

    Set lx_shrPathObj = CreateObject("scripting.filesystemobject")
    lv_shrPath = Replace(lx_shrPathObj.GetFile(lv_path).ShortPath, mv_longFilePathHelper, "")
    Set lx_wrkBkSrc = Workbooks.Open(Filename:=lv_shrPath, ReadOnly:=True)
    'Using lx_objectExcel.Workbooks.Open WORKS but not Workbooks.Open 
    'lx_objectExcel.Workbooks.Open(Filename:=lv_shrPath, ReadOnly:=True)
    If Not Library.DoesSheetExist(lx_wrkBkSrc, mv_workSheetName) Then
        GoTo ErrorHandling
    End If
    Set lx_wrkShSrc = lx_wrkBkSrc.Sheets(mv_workSheetName)


    'Rest of the function

End Function    

它将打开工作簿并立即退出VBA代码.我尝试了 https://support.microsoft.com/en-us/help/555263，但结果相同.

It opens the workbook and exits the VBA code immediately. I tried this https://support.microsoft.com/en-us/help/555263, but same results.

如果我使用新的Excel实例，它不会退出

It does not exit if I use new instance of Excel using

lx_objectExcel.Workbook.open('path')

我不想使用新实例，因为特殊粘贴不适用于新实例，以这种方式打开100册工作簿会浪费很多时间.

I do not want to use a new instance as paste special is not suitable with new instance and opening 100s of Workbooks this way consumes lot of time.
