Android SOLVED: Game crash after first Google Play login and after Achievements window closing

Hey.

There are two problems:

1) The game crashes after the first authorization in the Google Play Games. at the next launches, everything is fine.
2) the game crashes when you close the Google Play Games achievements window (opening works fine).

Both crashes occur without error.
In another game, there are no such problems.
Reinstall extensions don't solve the problem. But without extensions, everything seems fine.

Does anyone knew what could be the reason?

 

Solved. The problem was that the Facebook extension was added to the project, but it was not configured.
