COuld some 1 explain me how and why i got failed build please ?
Im unable to find your error within the logs becauee it is so long, try right clicking on the error log as soon as you start cooking your game and clear the logs, that way the only logs shown are the important ones regarding your error
It will greatly increase the chances of someone finding your error
Hi BearButter,
Try rebuilding your engine version and see if that addresses the error, if not, please let me know. Additionally, if it does not address the error, let me know what platforms/devices you are building for, what steps you are taking, and whether this occurs in a clean, blank project with no additional content or if it is limited to one project.
Thanks for your replying. Some how i fixed the error build. I think there are problems with the environment ( since i delete some object and tried build again, it works fine ) But i dont remember much about what i did 
Kinda playing around all setting …
I’m happy to hear you were able to fix your error. I am going to mark this as answered for tracking purposes. If you experience this error again, please comment with updated information.
