App Store doesn’t open on my MacBook pro.

Haven’t been able to update operating systems for a while. It’s a 2013 MBpro.

Whenever I click on the App Store icon, the App Store appears but it freezes( it shows the spinning disk in the top) I always use the “force quit” to close the App Store.

Everything else works fine. It’s not slow. I use it for internet, streaming, production and other things. I have no problem with the iTunes app or any other app on the laptop, I just can’t update anything. Suggestions?
