Navigator.getUserMedia and Navigator.webkitGetUserMedia undefined after updating to Chrome 74

After updating from Chrome 73 to 74 navigator.getUserMedia and navigator.webkitGetUserMedia return undefined.

Here https://developer.mozilla.org/en-US/docs/Web/API/Navigator/getUserMedia I see that getUserMedia is actually deprecated in favor of navigator.mediaDevices.getUserMedia(), but in my case navigator.mediaDevices too is undefined so I cannot use it.

Anyone knows if it's a bug in the latest release of Chrome or if I need to use something else?
