Two USB camera sessions not loading simultaneously - QT 6, Camera (QTMultimedia)

Hi everyone,

I have code of the form:

MediaDevices {
            id: mediaDevices
        }
Rectangle{
 width:1000
height:1000
CaptureSession {
                        id: captureSessionLeft
                        camera: Camera {
                            id: liveCam
                            cameraDevice: mediaDevices.videoInputs[0]
                            active: false



                            focusMode: Camera.FocusModeAutoNear

                        }
                        videoOutput: videoOutputLeft


                    }
                    VideoOutput {
                        id: videoOutputLeft
                        anchors.fill: parent
                        fillMode: VideoOutput.Stretch

                    }
}
}
Rectangle{
 width:1000
height:1000
CaptureSession {
                        id: captureSessionRight
                        camera: Camera {
                            id: liveCam2
                            cameraDevice: mediaDevices.videoInputs[1]
                            active: false



                            focusMode: Camera.FocusModeAutoNear

                        }
                        videoOutput: videoOutputRight


                    }
                    VideoOutput {
                        id: videoOutputRight
                        anchors.fill: parent
                        fillMode: VideoOutput.Stretch

                    }
}
}

Furthermore, I have tried using the .start() method for each capture session to load both cameras simultaneously. What I find is that I can only load one camera at a time, while the session that starts after is left blank.

Is there any way to fix this? Both of my cameras are USB cameras, and I have validated that I can access them.

For further context, I am running a MSVC 2019 build, on a Windows OS.

Thank you!
