Myoware EMG + Arduino - No Power Problem

Hi guys, this is my first time post in this forum.

I used myoware muscle sensor by advancer technologies and Arduino Uno. I just want to try the sensor. The problem is everytime I connect the (+) pin in myoware to the 3.3v pin to the Arduino Uno, the power on the Arduino always gone.

I’ve tried to use only the battery power on my laptop. But the result still same.

this is my video try to connect it
