Help to fix bug WebCam not initialized

Hello there how are you? Im in my first steps of learning to program in unity. I do have a project made in unity for webgl all runs really nice in unity editor, but when I build for webgl, the [login to view URL] file opens good, charge the unity bar and then the screen don't ask for the permission to use any webcam device. I got in developer tools on the chrome web browser: "WebCam not initialized". What I'm looking for a person to solve the small bug and teach me how to fix it. Thanks in advance.
