Help please - Android urho - Node handle changes each time

I’m using accelerometer to rotate my scene on android and it works well the first time .
Then when i push the app to the background and re-enter - it crashes . Same thing when i close the app and open again.

I think it has something to do with the way the urho app is being created/destroyed .
