Rust crash 2016-04-09_184012

Hi, I have played before in rust and everything was fine, did not crash and do not get out, but then I gave her a couple of months, I decided to play again. I play, play and after 5.10, 20 minutes later I crash and says “opps the gmae crashes the crash report folder named 2016 / -04-09_184012 next to game executable.” Help me, I do not know what the problem is.
