[WindowsMR][Emulation] - Trunk - Windows MR SDK is failing to Initialize when using simulation
When using simulation on the first fresh run of a project the Windows Mixed Reality SDK will fail to initialize because the HoloLens device couldn't initialize. This will cause simulation to fail and breaks automation and user cases.
Notes:
RS3 - 16299.248
Only Reproduces in trunk
Breaks Emulation
Breaks users and automation
If you restart the editor using the same project the bug will not reproduce
Repro Steps:
1.) Download the repro project
2.) Double check the assets folder is the only folder int he project folder
3.) Open the project
4.) Open Test Runner
5.) Go to play mode tests
6.) Run all tests
7.) Observe the tests fail and there is a warning message in the console log
Actual:
HoloLens device is failing to initialize when using simulation on a fresh/new project
