Issue with Xbox One Controller buttons

Hello,

For some time now I've been having some issues with the buttons on my Xbox One Controller, to be completely honest it works, it's just that from time to time, when I press the "kind of broken" button and it won't do anything, If I double click on A quickly
it won't always work...

Same for RT, sometimes when I press it, nothing happens, I have to click again to make it work...

How could I get it to work again ? I can play but it's boring, especially on specific games... I'm on PC by the way.

Thank you.

:)
