Help! My Razer Huntsman Mini Keyboard Isn't Typing

Hey everyone! I'm having a bit of a meltdown here because my Razer Huntsman Mini keyboard has suddenly stopped working properly. It's plugged in just fine, but when I try to type the alphabet keys, nothing happens! Instead, it seems like it's triggering random shortcuts in Firefox, like opening the search history or file browser. I've tested it in other apps too, and I'm having the same problem everywhere. I've been using this keyboard for about a month with no issues until today, so I'm really confused. Has anyone experienced this before? Any tips on how to fix it? Thanks a ton!
