Failed to open descriptor file error

No building errors
No packaging errors
I have tried to move the build folder to C://

We extracted our blueprint version to a C++ version
I have tried this "Go to WindowsNoEditor\Engine\Binaries\Win64

Then “UE4Game-Win32-Shipping” or “UE4Game-Win64-Shipping” in my case, rename it to your project name, which should be the same as in /WindowsNoEditor/YourProjectName.uproject"

Please help

Solved : We had earlier try to make a Blueprint project to a C++ project by copying the folders and having visual studio up, everything worked except to package and play the game with this error:

Solution : Followed this tutorial and everything works fine
