Description

ShooterGame crashes when loading into the match on Mac when that ShooterGame was packaged with Pak files.

The ShooterGame project was created using the Unreal Engine Launcher

I do not see this issue on Windows.
I do not see this issue when I do not use Pak files.

Steps to Reproduce

2. Open the ShooterGame project
3. Select Edit > Project Settings > Packaging
4. Ensure that the Use Pak File option is checked
5. Select File > Package Project > Mac
6. Select OK to choose a package location
7. Open the packaged ShooterGame.app
8. Select Host > Free For ALL

RESULT:
ShooterGame crashes when loading into the match
