Another iOS 13 Problem - AppRate

When i add AppRate plugin and set it in app.component, i can run it ın simulator but can not run in device. App does not open. XCode generates error:

[alertController addAction:[UIAlertAction actionWithTitle:[buttons objectAtIndex:n]

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: '-[NSNull length]: unrecognized selector sent to instance 0x1fd5879a0’

Anyone that can run AppRate on iOS 13?
