VBA: Workbooks.Save & Close not saving - excel

Question

I have the following code that is working but the line .close closes the WB without saving:
Option Explicit
Public Function updateStatus(fpath As String, fname As String, num As String)
Dim wk As String, yr As String
Dim owb As Workbook
Dim trow As Variant
With Application
.DisplayAlerts = False
.ScreenUpdating = False
.EnableEvents = False
End With
Set owb = Application.Workbooks.Open(fpath & fname)
trow = owb.Sheets(1).Range("Change" & num).Row
owb.Sheets(1).Cells(trow, 5).value = "Test"
With owb
.Save
.Close SaveChanges:=True 'This line doesn't seem to work
End With
With Application
.DisplayAlerts = True
.ScreenUpdating = True
.EnableEvents = True
End With
End Function
If I remove the line, the WB stays open and I see the change. If I add the line, and open the specific file, I see no change.

Answer 1

As mentioned in the comments, the code looks ok, you probably have some Data Protection enabled on your Excel, which does not allow the saving. Try to make a minimal example like this:
Option Explicit
Public Sub TestMe()
Dim owb As Workbook
Set owb = Application.Workbooks.Open("C:\Users\vityata\Desktop\Testing.xlsx")
owb.Save
owb.Close
End Sub
Then debug with F8 and see the message that you got, once you go pass by owb.Save.
Just that you know:
.Save
.Close SaveChanges:=True
With the .Save line you make the SaveChanges:=True part useless. And vice versa.
