Game keeps going to Unity Windows and then closes.

I have no idea, why at this point. The first time it happened to me was 2 days ago, i supposed it was due having a lot of mods, although my game had been running with no problems for more than a week, so going thru the forums, i made sure to disable all the mods i had, and started a new game, just vanilla. Kept playing for around 3 or 4 hours and then AGAIN, Unity Window pop-up
game crashed and was back to my desktop.. i have over 850 hours in the game, and loved it, is there a fix for this? please help.

Most of my game time was since 0.17 thru 1.0, i never had the game crashed like that. Is this something due to the 1.1 update? is there a fix? or should i go back 1.0 ? ( i am playing on steam )

Not sure what you mean with Unity window.
It is the crash window that tells you about the crash and that it create a crash folder ?
Then just zip that folder/files from it and attach it to your answer that might give a hint about the crash.
