When I launch the game, steamvr opens making it lag a lot and I can't exit steamvr without shutting down the game. It doesn't seem to have steamvr support so I'm not sure why it would open it.
The engine is packaged with SteamVr because it is the native plugins provided with Unreal Engine 4, however, unfortunately, it was causing some issues that was preventing me from packaging the game when disabled. So my recommendations would be to turn off steam or disable steam vr if possible so it doesnt run.
