Evita erro de 'Erro em tempo de execução' 7 'sem memória' no Excel ao usar macro

Question

Eu continuo recebendo este erro sempre que eu executar uma macro no meu arquivo de excel. Existe alguma maneira de evitar isso? Meu código está abaixo. A depuração destaca a seguinte linha como o problema:

ActiveSheet.Shapes.SelectAll

Minha macro:

Private Sub Save()

Dim sh As Worksheet

ActiveWorkbook.Sheets("Report").Copy 'Create new workbook with Sheets("Report"(2)) as only sheet.
Set sh = ActiveWorkbook.Sheets(1) 'Set the new sheet to a variable. New workbook is now active workbook.
sh.Name = sh.Range("B9") & "_" & Format(Date, "mmyyyy") 'Rename the new sheet to B9 value + date.
With sh.UsedRange.Cells
    .Value = .Value 'eliminate all formulas
    .Validation.Delete 'remove all validation
    .FormatConditions.Delete 'remove all conditional formatting
    ActiveSheet.Buttons.Delete
    ActiveSheet.Shapes.SelectAll
    Selection.Delete

    lrow = Range("I" & Rows.Count).End(xlUp).Row 'select rows from bottom up to last containing data in column I
    Rows(lrow + 1 & ":" & Rows.Count).Delete 'delete rows with no data in column I
    Application.ScreenUpdating = False
    .Range("A410:XFD1048576").Delete Shift:=xlUp 'delete all cells outwith report range
    Application.ScreenUpdating = True

    Dim counter
    Dim nameCount

    nameCount = ActiveWorkbook.Names.Count
    counter = nameCount
    Do While counter > 0
    ActiveWorkbook.Names(counter).Delete
    counter = counter - 1
    Loop 'remove named ranges from workbook

End With
ActiveWorkbook.SaveAs "\Marko\Report\" & sh.Name & ".xlsx" 'Save new workbook using same name as new sheet.
ActiveWorkbook.Close False 'Close the new workbook.
MsgBox ("Export complete. Choose the next ADP in cell B9 and click 'Calculate'.") 'Display message box to inform user that report has been saved.

End Sub
