JVC PC-X100 not rewinding or fast forwarding.

I just picked up a JVC PC-X100 from goodwill and noticed that it will not rewind or FF tapes on either side. I don’t know anything about how cassette players work so I figured I’d ask here and see if it’s an easy fix! 🤞

In the video, the first few attempts are with me pressing and releasing the rewind button (it stays down for a moment and then pops back up), and after that I’m holding the button down
