AssetsManager problem

I use cocos2d-x v3.15. for js-game on Android.
I want to use AssetsManager for hot updates. I can download resources and the game starts.
But when I exit the game and try to open again. game crashes.
On a rooted phone i see that the recources are gone from the download folder.

In Android studio :

06-22 20:38:43.766 30439-30649/org.cocos2dx.APK315 D/cocos2d-x debug info: find in flash memory dirPath(/data/data/org.cocos2dx.APK315/files/Common/Common/)
06-22 20:38:43.766 30439-30649/org.cocos2dx.APK315 D/cocos2d-x debug info: find in flash memory dirPath(/data/data/org.cocos2dx.APK315/files/Common/Common_temp/)
06-22 20:38:43.836 30439-30649/org.cocos2dx.APK315 D/cocos2d-x debug info: find in flash memory dirPath(/data/data/org.cocos2dx.APK315/files/Common/Common/)
06-22 20:38:45.108 30439-30649/org.cocos2dx.APK315 D/cocos2d-x debug info: ALREADY_UP_TO_DATE

this path is my storagePath.

var storagePathEnd = “Common/Common/”;
var storagePath = ((jsb.fileUtils ? jsb.fileUtils.getWritablePath() : “/”)+storagePathEnd);

AssetsManager deletes the folders when I start game for the second time

Please Help!!!
