How to run macro with project locked?

Hello, I have a spreadsheet whose project has a password, but I want the macros to work and if the user tries to enter the macros they will have to enter the password (which I put in the project).

I put a code that unlocks the spreadsheet upon entering, it looks like this:

Option Explicit

Private Const PAGE_EXECUTE_READWRITE = &H40

Private Declare PtrSafe Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As LongPtr, Source As LongPtr, ByVal Length As LongPtr)

Private Declare PtrSafe Function VirtualProtect Lib "kernel32" (lpAddress As LongPtr, ByVal dwSize As LongPtr, ByVal flNewProtect As LongPtr, lpflOldProtect As LongPtr) As LongPtr

Private Declare PtrSafe Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As LongPtr

Private Declare PtrSafe Function GetProcAddress Lib "kernel32" (ByVal hModule As LongPtr, ByVal lpProcName As String) As LongPtr

Private Declare PtrSafe Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As LongPtr, ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer

Dim HookBytes(0 To 5) As Byte
Dim OriginBytes(0 To 5) As Byte
Dim pFunc As LongPtr
Dim Flag As Boolean

Private Function GetPtr(ByVal Value As LongPtr) As LongPtr
    GetPtr = Value
End Function

Public Sub RecoverBytes()

    If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6

End Sub

Public Function Hook() As Boolean
    Dim TmpBytes(0 To 5) As Byte
    Dim p As LongPtr
    Dim OriginProtect As LongPtr

    Hook = False

    pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")


    If VirtualProtect(ByVal pFunc, 6, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then

        MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6

        If TmpBytes(0) <> &H68 Then

            MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6

            p = GetPtr(AddressOf MyDialogBoxParam)

            HookBytes(0) = &H68
            MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4
            HookBytes(5) = &HC3

            MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6
            Flag = True
            Hook = True

        End If

    End If

End Function

Private Function MyDialogBoxParam(ByVal hInstance As LongPtr, ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer

    If pTemplateName = 4070 Then
        MyDialogBoxParam = 1
    Else
        RecoverBytes
        MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, hWndParent, lpDialogFunc, dwInitParam)
        Hook
    End If
End Function

This code runs when you open the worksheet (#

Would anyone have a macro to help me with this? Maybe KeyCode. Or a UserForm.

This is the error that happens:
