Why doesn't getUserMedia work in chrome?

Question

JavaScript

Why doesn't this code work in Google Chrome browser?

navigator.mediaDevices.getUserMedia({ video: true })
          .then((stream) => {
            stream.getTracks().forEach((track) => track.stop());
            this.loadCameras();
          })
          .catch((error) => console.log(error));

Camera access is requested and an error appears in the console

DOMException: Could not start video source

What could be the problem?
Everything works in Firefox.
