Error Unknow Cook Failure

Hi guys,
I’m trying to pack my project for windows 64 but still got an unknow cook failure. I already:
  - resolved all other errors that existed in the output log
  - check and recompiled some of my major blueprints
  - restarted my pc
  - canceled saved, intermediate and config folders

The last time i had an unknow error while packing i had to migrate the assets to another project to avoid the issue. But, if I have to do that every time, it would be problematic. Expecially if the game become more and more complex.
Someone have a special trick in the sleeve?

The previous output log file was related to some wrong project settings that i reset to default. Here my usual log split in 2 parts’ cause exceeding the Mb limit

SOLUTION:
In the log files there recurrent errors saying "Failed to load “…/ThirdPersonBP/Maps/ThirdPersonExampleMap.uasset”. This .uasset was an old build of the original UE4 template that was used to start the project, that later was renamed and moved from that folder. Though it was deleted, a corrupted version has remained in place, invisible in the editor for the fact of being corrupted. I deleted it manually in the project folder and the issue is now solved. Check it out if you get into the same problem.
