Copy rows to another workbook - excel

Question

This code worked once and then stopped. It runs with no action or errors.
I would like if column "a" of the "export" sheet has a yes to copy the cells from B to J to the next clear line in workbook MOSTEST sheet1 (named 11.2022).
Sub DateSave()
Dim LastRow As Integer, i As Integer, erow As Integer
LastRow = Worksheets("EXPORT").Range("A" & Rows.Count).End(xlUp).Row
For i = 1 To LastRow
If Cells(i, 1).Value = "YES" Then
Range(Cells(i, 2), Cells(i, 10)).Select
Selection.Copy
Workbooks.Open Filename:="F:\Orders\MOSTEST.xlsx"
Worksheets("11.2022").Select
erow = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row
ActiveSheet.Cells(erow, 1).Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
ActiveWorkbook.Save
ActiveWorkbook.Close
Application.CutCopyMode = False
End If
Next i
End Sub
If changed the "Worksheets("11.2022").Select" to sheet1 which I would prefer as I wouldn't have to change it every month.

You should try to avoid using select, see other post
I adjusted your code where needed, I'm still trying to figure out best practice (i.e. it would be better adding the cell ranges to a range variable and then pasting them in one go but I'm not quite there yet) when it comes to minimizing code so if others can do better, feel free :)
Sub DateSave()
Dim LastRow As Long, i As Long, erow As Long
Dim wsStr As String
Dim ws As Worksheet, wsC As Worksheet
Dim wb As Workbook, wbM As Workbook
LastRow = Worksheets("EXPORT").Range("A" & Rows.Count).End(xlUp).Row
Set wb = ActiveWorkbook
Set wsC = wb.Sheets("EXPORT")
Workbooks.Open Filename:="F:\Orders\MOSTEST.xlsx" 'Don't keep opening and saving/closing your workbook per copy, that would heavily increase runtime
Set wbM = Workbooks("MOSTEST.xlsx")
wsStr = Month(Date) & "." & Year(Date)
Set ws = wbM.Worksheets(wsStr) 'If your currentmonth will always be the first sheet then you can use wbM.Sheets(1)
erow = ws.Cells(Rows.Count, 1).End(xlUp).Row
wb.Activate
For i = 1 To LastRow
If wsC.Cells(i, 1).Value = "YES" Then
erow = erow + 1
wsC.Range(wsC.Cells(i, 2), wsC.Cells(i, 10)).Copy 'avoid select
ws.Range("A" & erow).PasteSpecial xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
End If
Next i
wbM.Save
wbM.Close
Application.CutCopyMode = False
End Sub
