Unknown Cook Failure

I’ve been trying to package a project for Win64bit in 4.16, 4.17, and now 4.18 but it always hangs after at the end of cooking. Last night i let the package process run for an hour and got a bunch of “LogWindows: Error” and exit code 3 followed by exit code 25.

I have installed all the visual studio plugins I can find that might be useful.
What am I doing wrong here?

Here’s my log: link text

Ok so I fixed this myself by migrating the level to a new project. Once I did that it I had to re-enable the substance plugin, fix a few blueprints errors and it was good to go.
