Often crashes (Terraria)

The game often crashes with this error and crashes absolutely randomly, it can pop up after hours of play or after 5 minutes, sometimes it happens when over the course of the game several times so I now I can't kill the Queen slug, only you will call, and immediately throws this error as well sometimes if I move fast, I don't know what to do, already beginning to hate, I was beaten like that skeletron Prime, he had a little health is already stupidly flew this error, was this error I once found a sharp sword and took stupid mistake and this sword is certainly not preserved, does not normally play.
