Windows 10: Backspace and enter key not working

I was playing games with my friends, and I was trying to say something in chat when suddenly the enter key won't work. I was trying to tell my friends that my backspace and enter keys won't work. So I searched on youtube on how to fix this problem, but none of those work, sticky keys, updating the driver, nothing. I even searched the web on how to fix it, but it still won't work, so I came here to ask for some help. Thanks.
