Razor Huntsman shocking wrists

I’ve seen other people have this problem, it’s been doing electric shocks on my wrists like every 10 seconds whenever I rest my wrist on the attachment keyboard rest that’s metal. I tried plugging it into different grounded house outlets and usbs and nothing works. It’s been doing it since I bought it less than a year ago. I even put electrical tape around the keyboard rest and it still zaps me. WHAT IS THE FIX FOR THIS?
