v2.2b3 InvalidHandle Errors when enabling SteamVR at runtime

WIndows 10 Unity 2017.3.1f1 SteamVR v2.2b3

If you start a without SteamVR and then load SteamVR and a Camera Rig, SteamVR will throw the InvalidHandle errors. You can repro this with the SteamVR_ForceSteamVRMode Scene

Repro Steps:

1. Open the SteamVR_ForceSteamVRMode Scene
2. Play The Scene
3. Wait 1 second for SteamVR to be loaded

Expected Behavior: VR shoudl start normally without errors

Observed Behavior SteamVR throws a bunch of errors to the console

I believe I’ve got a better fix for this in b4. I’m suppressing the automatic update calls that are made the same frame that steamvr input starts. https://github.com/ValveSoftware/steamvr_unity_plugin/releases/tag/2.2b4

For anyone having this issue ensure that you have the [CameraRig] with both controllers present and enabled.

When I disabled the controllers my input stopped functioning. If you don’t want the controllers visible disable the Model child instead.

This didn’t work for me. What did work instead was regenerating the “StreamingAssets/SteamVR” folder. Good luck!
