Unsolved Camera stops NFC from working (QML, QT5.12.6)

[UweA]

If I add "Camera" to my qml file NFC stops recognising NFC tags if the target device runs Android11. Android10 seems to work.
That is my code:

import QtQuick 2.12
import QtQuick.Window 2.12
import QtNfc 5.12
import QtMultimedia 5.12

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    NearField {
        property bool requiresManualPolling: false
        orderMatch: false

        onMessageRecordsChanged: {
            console.log("NFC-LOG: onMessageRecordsChanged")
        }

        onPollingChanged: {
            console.log("NFC-LOG: onPollingChanged")
            if (!polling && requiresManualPolling)
                polling = true; //restart polling
        }

        Component.onCompleted: {
            console.log("NFC-LOG: onCompleted")
            if (!polling) {
                requiresManualPolling = true;
                polling = true;
            }
        }
    }

    //Camera {
    //    id: camera
    //}
}

If I activate the last three lines (Camera) NFC does not recognise tags anymore.

Any idea how to solve that? Seems to be a Qt bug...

Same is true for demoproject "corkboards". Add Camera and NFC is dead.

Have you found a workaround for this problem?

[UweA]

@davidovv Unfortunately not with Qt. I switched to a native app what solves it.

Hi,

I would say this warrants a bug report if there's not one already.
