Games made by Unity crashing

This isn't a bug ON Unity, it's a bug ABOUt Unity.

I can't play any games made with Unity. When I launch the games I can walk around for a few seconds and then the game goes to "Not answering". Here are the games that I've played:

7 days to die ,CHKN ,Starsone ,Who's your daddy

All those games crashes when I try to play them, and I have atleast the recommended specs for all those games, as I can play games like Dying Light without any problems.

Thanks!
