Paste Special error 1004 PasteSpecial method of Range class failed - vba

Question

I have looked thoroughly at the current answers for this problem and none of them have fixed mine.
The operation is simply copying a selection of a sheet and copying to a new book called budget.
Again I have tried multiple different ways of doing the same thing and none of them seem to change this error. The select method works,it only breaks when I try to paste.
Code:
Range("B3").Select
Range(Selection, Selection.End(xlToRight)).Select
Range(Selection, Selection.End(xlDown)).Select
Selection.Copy
Dim wk As Workbook
Set wk = Workbooks.Add
wk.SaveAs FileName:=ThisWorkbook.path & "\" & "Budget.xlsx"
wk.Activate
wk.Unprotect
wk.Worksheets("Sheet1").Range("B3").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
Thanks,

Answer 1

If you try exactly the steps in the code manually, you will find it also fails. The issue is that inbetween copying the cells and trying to paste them, you are creating a new workbook and saving it. This cancels copy/paste mode (i.e. the "marching ants" around the copied range disappear), so there is nothing to paste.
The solution is to not use Selection at all. In general any time you find yourself writing .Select in VBA you're doing it wrong (see this question for detail). Here is how I would re-write your code:
Dim wk As Workbook
Set wk = Workbooks.Add
wk.SaveAs Filename:=ThisWorkbook.Path & "\" & "Budget.xlsx"
ThisWorkbook.Range("B3").CurrentRegion.Copy
wk.Worksheets("Sheet1").Range("B3").PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False

Try the code below (explanation inside the code as comments):
Dim wk As Workbook
Set wk = Workbooks.Add
wk.SaveAs Filename:=ThisWorkbook.Path & "\" & "Budget.xlsx"
wk.Activate
wk.Unprotect
' have the Copy>>Paste section together
Dim LastCol As Long
Dim LastRow As Long
' you never mentioned which sheet to copy from, I used the first index
With ThisWorkbook.Sheets(1)
LastCol = .Range("B3").End(xlToRight).Column
LastRow = .Range("B3").End(xlDown).Row
.Range("B3", .Cells(LastRow, LastCol)).Copy ' <-- Copy without Select
End With
' Paste without Select
wk.Worksheets("Sheet1").Range("B3").PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
:=False, Transpose:=False
