[Help] How to make # undetected

I recently done creating a TeamESP #. but Blackshot it will auto close when Im pressing the hotkey in a room. Im using the .flt injection method.

This is the source code. I hope anyone could help me

Code:
#include <Windows.h>


#define ADR_PlayerPointer 0x00000
#define ADR_TEAMESP 0x00000
#define OFS_TEAMESP 0x61
#define BYTE1 0x01
#define BYTE2 0x00
#define Zero 0
#define One 1

bool Variavel[MAX_PATH], VariavelEsp = false;

void TeamEsp()
{
while (1)
{
if (GetAsyncKeyState(VK_INSERT) & 1) //VK_(hotkey)
VariavelEsp = !VariavelEsp;

if (VariavelEsp)
{
*(BYTE*)(*(DWORD*)(ADR_PlayerPointer)+OFS_TEAMESP) = One;
*(BYTE*)(ADR_TEAMESP) = BYTE1;
if (GetKeyState(VK_LBUTTON) < 0)
{
*(BYTE*)(*(DWORD*)(ADR_PlayerPointer)+OFS_TEAMESP) = Zero;
*(BYTE*)(ADR_TEAMESP) = BYTE2;
Sleep(3);
}
}
else
{
*(BYTE*)(*(DWORD*)(ADR_PlayerPointer)+OFS_TEAMESP) = Zero;
*(BYTE*)(ADR_TEAMESP) = BYTE2;
if (GetKeyState(VK_LBUTTON) < 0)
{
*(BYTE*)(*(DWORD*)(ADR_PlayerPointer)+OFS_TEAMESP) = One;
*(BYTE*)(ADR_TEAMESP) = BYTE1;
Sleep(3);
}
}
Sleep(5);
}
}

BOOL APIENTRY DllMain(HINSTANCE hinstDLL, DWORD _CallReason, LPVOID lpvReserved)
{
switch (_CallReason)
{
case DLL_PROCESS_ATTACH:
CreateThread(0, 0, (LPTHREAD_START_ROUTINE)TeamEsp, 0, 0, 0);
MessageBoxA(0, "CreditsHacker.Zone, anyonstopus, Xjemy2001, and Proeggby ) ", "# Succesfully Loaded !", MB_ICONINFORMATION); //messagebox
}
return 1;
}
