Assertion when attempting to package a map with nativized assets

Developer Notes

This is a duplicate of UE-44112

Description

Cannot package project with nativized assets. I am encountering an assert. This was encountered while verifying UE-43634

This is a Regression from 3378653

Steps to Reproduce
  1. Open QAGame
  2. Open Project Settings > Packaging
  3. Uncheck Use Pak File
  4. Expand the advanced settings under Packaging
  5. Add /Game/Maps/Framework/AI/QA-AI map by selecting the + next to List of maps to include in the package build
  6. Still in Packaging, under Blueprints, change Blueprint Nativization Method to Inclusive
  7. Package the project

Result: The package fails with an assert

Expected Result: The package successfully completes and is placed at the desired destination
