Unity - Google Play Services - Leaderboard UI crashing

Hello. I have a problem with Google Play Services - Leaderboard. Play Services works fine, but when a score is added to Leaderboard, Leaderboard UI is autmatic closed. This problem occurs both in the test and in the official versions of the game. Google Play Console will record the error, but without details.

Code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using GooglePlayGames;
5. using GooglePlayGames.BasicApi;
6.  
7. public class LeaderboardScript : MonoBehaviour
8. {
9.    
10.     void Start ()
11.     {
12.         PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().Build();
13.         PlayGamesPlatform.InitializeInstance(config);
14.  
15.         PlayGamesPlatform.Activate();
16.         SignIn();
17.     }
18.  
19.     void SignIn()
20.     {
21.         Social.localUser.Authenticate(success => { });
22.     }
23.    
24.  
25.     public void LeaderboardButton()
26.     {
27.         if(Social.localUser.authenticated)
28.         {
29.             PlayGamesPlatform.Instance.ShowLeaderboardUI();
30.         }
31.         else
32.         {
33.             SignIn();
34.         }
35.     }
36.  
37.     public void AddScoreToLeaderboard(long score)
38.     {
39.         Social.ReportScore(score, GPGSIds.leaderboard_highscore, success => { });
40.     }
41. }
42.  

Thanks a lot

 

Btw. I use Google Play Services 0.9.38. Versions larger than 0.9.38 dont work at all.
