path to copied workbook problem

I have the following situation: A file - fisierzero.xlsm that is on the Desktop, and two other files: one in the laminate folder named laminate.xlsm and one in the monolit folder named monolit.xlsm.
I guess I do not give the correct path in the VBA code because I have error 9 out of range error. all files are open.

Private Sub Worksheet_Change(ByVal Target As Range)

    Dim wb     As Workbook
    Set wb = ThisWorkbook
    
    Dim keycells As Range
    Set keycells = Range("A:Z")
    
    Dim wb2    As Workbook
    Set wb2 = Workbooks("E:\monolit\monolit.xlsm")
    
    Dim wb3    As Workbook
    Set wb3 = Workbooks("E:\laminat\laminat.xlsm")
    
    Dim ws     As Worksheet
    Set ws = wb2.Sheets("Sheet1")
    
    Dim ws2    As Worksheet
    Set ws2 = wb3.Sheets("Sheet1")
    
    If Not Intersect(keycells, Range(Target.Address)) Is Nothing Then
        ws.Range(Target.Address).Value = wb.Sheets("Sheet1").Range(Target.Address)
        ws2.Range(Target.Address).Value = wb.Sheets("Sheet1").Range(Target.Address)
    End If
End Sub
