Cap.findDevice return all time undefined

I try to work on packet with cap but is not work. I have try the default code :

const Cap = __cap.Cap
const decoders = __cap.decoders
const PROTOCOL = decoders.PROTOCOL

var c = new Cap();
var device = Cap.findDevice('192.168.0.10');
var filter = 'tcp and dst port 80';
var bufSize = 10 * 1024 * 1024;
var buffer = Buffer.alloc(65535);

console.log(device);

But every time Cap.findDevice return undefine. I have install npcap with WinPcap compatibility. I have try to a lot of different ip but no one work.

Some one have an answer ?

Thank in advance. Have a good day.
