Do the Vuforia Sample Applications show the same behavior?:

In this case you need to debug your application code and see if there is anything potentially wrong in the initialization phase.

One thing you may also want to try is to go back a few steps and remove the ARCamera from the scene and re-add a new ARCamera instance; after this, if you have any custom scripts or components that were attached to the ARCamera (or to its Camera child object), you can gradually reattach those and see at which point you start seeing the crash.

Yes, the sample works, so I think something wrong I did.

Can you reproduce this with one of the Vuforia Samples ?
