Packaging Error : Couldn't update resource

Hi, I have this message everytime I try to build my game. I’ve found this post https://answers.unrealengine.com/questions/207655/packaging-error-couldnt-update-resource.html but it doesn’t help me, all files in my project are writable, even the Epic folder and because the log only end with “Unknown Error”, I really don’t know where is the problem.

Can anyone help me with this please? I can’t package my game

Same problem here with 4.14.P3
