Packaging Error - Cook is failing

Development Platform & Builds

Using UE version 4.7.6, our project is failing during the cooking process. The stack trace it seems to give ends with a call of KERNELBASE.DLL!UnknownFunction

Have tried checking the project out from our source control, restarting the computer and building on a different computer.

Log files since all the posts read seem to ask for them, but none seem to have the specific problem we’re facing.

Does anyone have an idea where we should be looking to enable packaging?

Here is what is in the output log when the packaging process fails to complete.

There appears to be something wrong with one of your files.
You could try moving it to a different location (outside the project directory) to confirm it’s the problem.
If it is then try loading it in the editor and see if it can be repaired.

Thank you very much, that was exactly the problem. It didn’t seem to spit out any errors directly related to that ImpactRock asset, didn’t know if that would have been the problem due to multithreading.

For some reason the asset did not exist in the Unreal editor itself and we have just removed the file from the directory.
