[Help] Glass Walls keep crashing cannot find a fix?

[®Jack]

void main()
{
          
while(true)
{

				memcpy((LPVOID)0x57207A, "\x6A\x01", 2);
			
				memcpy((LPVOID)0x57207A, "\x6A\x00", 2);

All else that was on when testing

 //Hide Weapons
PushToConsole("drawguns 1");
PushToConsole("ShowBreath 1");
PushToConsole("ShowFps 1");

Am i suppose to add the SDK folder to my project properties for the glass walls? Not sure why im crashing o.O
