It only seems to be this user's game that crashes when he packages or does launch on windows
I have reproduced this locally. I honestly don't know why this repro's, but I have an example project and instructions from the user.
Example Project: [Link Removed]
1. Download Test Project from location in description
2. Attempt to Launch On Windows from the toolbar
Result: The editor doesn't crash, but the game it is launching crashes.
