Strange crash when run outside of debugger on Windows 10

[rcx]

Hello, thanks for your project. This is really great.

I'm trying to use the library on Windows 10 64-bit. Under Visual Studio's debugger or WinDbg, the program runs fine. When I run it from explorer or cmd, it crashes. To test, I am using the sample program provided, compiled with VS 2017 build tools. It also crashes when compiled with VS 2015 build tools. I tried compiling it myself and using the precompiled dll.

Interestingly, GetModuleHandle64 seems to work fine, but other functions like ReadProcessMemory64 or WriteProcessMemory64 cause a crash.

Some example code:

	printf("hello world\n");
	DWORD64 ntdll = GetModuleHandle64(L"ntdll.dll"); // OK
	printf("ntdll 64 = %llx\n", ntdll);
	HANDLE hProcess = GetCurrentProcess();
	char mem[10];
	BOOL succ = ReadProcessMemory64(hProcess, ntdll, mem, sizeof(mem), NULL); // crash

My Windows version is 10 Enterprise LTSC / 10.0.17763 Build 17763

I attached an compiled exe that is causing the crash here. This is the sample program. main.zip
