I experience this as well. From videos of it running on Windows, it looks like that is more or less the end of the tutorial itself, with the core offering some closing dialogue and leaving you to make balloons and shoot lasers as much as you want before quitting the application yourself.
Per "- VR Tutorial: Closing the system menu does not resume the tutorial" in the 2017-03-20 SteamVR update, this issue should be resolved.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
When running the tutorial, the core asks to press to system menu to bring the dashboard. Then it asks to press it again to close it. Then the core stands there saying nothing like an idiot. I suppose the tutorial is not finished or it would be a terrible ending.
