error that closes the game in game

YueJV

This error / bug has arisen twice since the last update (before that it had not happened) I am simply 
in the middle of a game and this window appears indicating that it will close because modifications 
have been detected in the game files (thing I've never done it because I've never moved / deleted or changed
any game file.
I hope they solve this problem soon or tell me how to solve it if it is only my case, thanks
