Unreal Engine 4.11 Preview

Hi guys!
I’m having difficulties to test my (Advanced Vehicle Kit) project in 4.11 Preview 3.
I’m experiencing something really strange, which i also have reported on the answershub (4.11 quits without error or log - Blueprint - Epic Developer Community Forums).
In sort, the problem is that, when i press play and start driving around with the car, the direction doesn’t matter, after a few meters it will instantly quit and leaving me without any error/bug or log report, so i can’t find the cause of this problem.
Here is the video:
What can i do in this situation?
