offline map crash on Android R

I want to load offline map on the Android R, the qml is as follow.

import QtQuick 2.0

import QtQuick.Window 2.0

import QtLocation 5.6

import QtPositioning 5.6 

Window {

width: 1920

height: 1080

visible: true 

Plugin {

id: mapPlugin

name: "mapboxgl"

PluginParameter

{ name: "mapboxgl.access_token"; value: "xxxxxxx" }

PluginParameter

{ name: "mapboxgl.mapping.cache.directory"; value: "/storage/emulated/10/Download/offline-maps" }

PluginParameter

{ name: "mapboxgl.mapping.cache.size"; value: 100 * 1024 * 1024 }

} 

Map

{ id: map anchors.fill: parent plugin: mapPlugin center: QtPositioning.coordinate(52.53471566, 13.29339621) activeMapType: map.supportedMapTypes[map.supportedMapTypes.length-1] zoomLevel: 14 }

}

this demo can work on Android Q， but it will crash on Android R.
