App crashes with collisionobject (Mac)

Hi, I’m doing the first tutorial (side-scrolling) and every time that I add a shape to a collisionobject the engine has crashed. Not really sure If It’s because of the collisionobject or the shape.
If It’s useful I can upload the Error report generated after forcing the closure of the app.

I would like to take this opportunity to thank you for inviting me to beta, the engine transmits very good feelings so… Congrats and best wishes polishing and improving it!

Could you please describe exactly the steps you go through, from opening the project until the crash (or record a video).
