Running a VR template packaged game with -nohmd results in an AudioDevice crash

Running a VR template packaged game with -nohmd results in an AudioDevice crash

Description

Running a VR template project with -nohmd causes the packaged game to crash on launch. Running with just -vr doesn't result in a crash.

Tested in //UE4/Release-4.25 @ CL 14469661 and did not encounter a crash with -nohmd, so marking as a Regression

Steps to Reproduce
  1. Create a new VR Template project
  2. Package the project for Windows
  3. Open the Command Prompt window
  4. Enter "location of your VR package .exe" -nohmd -vr into the command prompt

RESULT:

The package crashes on launch

EXPECTED:

The package would open without crashing
