I emailed Ludei about this situation we're having, and this was their reply to me
"After some investigations here, we've detected that Construct 2 plugin for physics performs some changes on our JavaScript exception code base.
We're speaking with Ashley from Scirra, because this change makes the physics on Construct 2 unusable, but it's a Construct 2 issue. And it's out of our control.
Thank you."
