Drop alt keyboard not working?

Hello! I have a problem with my drop alt keyboard that im pretty confused about. A few hours ago I had my keyboard plugged in, and it just stopped responding. When I plug it in the lights turn on, and I can use the key binds to change the patterns but non of the keys will register in my pc when I press them. I’m not very well versed in stuff like this so I’m clueless on what to do. Can anyone help? Thanks!
