Description

The latest 4.13 Binary Gamedev engine crashes on launch with a SteamVR callstack. This crash only occurs in Binary, I was unable to reproduce this crash in Github.

This issue looks as though it may be related to trying to initialize SteamVR HMD on startup of the editor, and crashing. We have one user on EngineQA who has the HMD attached and SteamVR installed who is not receiving this crash when launching the editor.

Steps to Reproduce
