Game crash in run time

hello,

i've made i little game demo, all working fine in editor.

But the exe build do not work completely fine. The game crashes in a specific level at random places.
The crash : the game window poof, no message, and the game is no more.
That same level works perfect in editor.

I have no idea how to figure out why its crashing.

How do i need to proceed ?

thanks

 

thank you, the problem is gone with the lastest unity update
