Just got a Vice. Muze bullet cap stuck in the on position. Help?

So overall this is all in all an okay experience. I ordered a Vice sold by Amazon on Amazon and just got it in the mail today. The Muze, the silver vibrating bullet that inserts into the toy, has a malfunctioned cap piece. I was able to cycle only 2 patterns until the button got stuck in the on position and won’t release. I called aneros and they said they sold the Muze separately for $100, and none of its parts individually were sold. I messaged Amazon support and they gave me a full refund on my purchase and said I did not need to send anything back (this blew my mind) but they are currently out of stock so they wouldnt be able to replace it anyways. Regardless, I now have a free Vice with a broken Muze button. Does anyone know how I could fix it?
