win32 GUI not loading properly after adding an edit window - c++

Question

When I build the program in visual studio It takes a long time to build and does not display properly, during this proccess it loads and unloads lots of what appears to be dll files in the console. If I remove the one line that starts with CreateWindowW(L"EDIT" the program will run perfectly. I have read through the documentation and I cant find what is wrong with it. Any help is appreciated.
Here is full code
#ifndef UNICODE
#define UNICODE
#endif
#include <windows.h>
#include<iostream>
#define file_menu_new 1
#define help_menu 2
#define file_menu_open 3
#define file_menu_exit 4

Add wc.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1); and remove WM_PAINT. If you don't set a class background you need to handle WM_ERASEBKGND or otherwise validate the background color painting.
