Unknown Cook Failure

When trying to package my game for distribution, the build fails and I get an error called “PackagingResults:Error: Error Unknown Cook Failure”, and I’m not sure what’s causing it. My best guess is it’s trying to find old references to assets that were deleted, but I wouldn’t know why it’s trying to do so or how to clear those references. Maybe a Fix Up Redirectors will help?

The output log was too large to attach, but I’ve included the automation log it’s referencing.
