The boards are individually tested in manufacturing. And I don't see any issues with your soldering. So a hard short seems unlikely.

The board does have > 120 uF of bypass capacitance between +5v and GND. So current will flow between these pins until the caps all charge up. Your multimeter is most likely interpreting the capacitor charging current as a short.

But I only happens when i plug in my Leonardo

What exactly happens when you plug it into the Leonardo?

My 5v an ground start smokeing and my loenardo slowly dies

OK. That is unusual. But we can authorize a replacement. Please contact Amazon for a replacement board and be sure to include a link to this thread.
