MCPE crashes and freezes without internet connection

When I play with internet connection I don't have any problem with the game, but since I updated to the 1.2.2 version, y can't play without internet connection.

First I enter to the game normally, select a world and can play about one minute , but then my game to crashes and this freezes, I can't make nothing, only force output, closing the process.

Please Help me.
Sorry for my bad English.
