Happens in 4.24 and 4.25
Everything works fine in editor. It’s only when packaged.
Steps to reproduce: Start a first person project. Add third person content. Add code to Open Level ThirdPersonExampleMap (I think) when pressing spacebar.
Effect when in editor: as expected
Effect when packaged: a long hang when the level should change instantly, a black screen on getting back. Black screen is because VR headset isn’t on. Putting it on lets you see the game is now in VR mode.
