Top outlet socket doesn't work, but bottom one does

One of my outlets in my home has recently failed on me. The bottom one works fine but the top doesn't. I previously had LED light strips plugged into the top but when I tried to turn it on, it didn't work. Also tested other multiple devices with that socket with no luck.

I have no electrical knowledge and was wondering if anyone has any advice on how to fix it. Do you think I should go to my local Home Depot and buy a new one to install? If so, I'll be searching for a guide on youtube or somewhere. Thanks!
