I am developing with Unity2017.4.34f1 using Vive pro eye.
In the project I developed, scene transitions occur frequently, but at that time, an error [[SRanipal] Initial Eye: DEVICE_NOT_FOUND] occurs and the eye tracking function stops responding.

Please help me if you know the cause or solution of this problem. Thank you!

Thank you for your reply.

It is not always reproduced. It will be reproduced occasionally.

The test scenario is as follows.
1. Scene A starts with the target displayed in front of the user.
2. The user looks at the target for 1 second (scene A).
3. Move to scene B with 10 objects displayed at random positions.
4. Success when the user finds the target from within the object and gazes at the target for 1 second (Scene B).
5. Repeat 1 ~ 4. 10 times.
