When I press any button on the Oculus Touch Unity 5 crashes

I’ve just setup Unity 5 Oculus Utilities and Avatar SDK. I can play with the Oculus and Oculus Touch. It works perfect. When I press down to any button on the Touch Controllers, Unity 5 crashes. How can I fix this issue?

I find a solution to my problem, my unity version is 5.5.2. There is something wrong with the OVRAvatar SDK. Download the newest SDK for OVRAvatar, re-import it and it should be fixed.
