Xbox Series X controller stick drift and missing inputs?

I've had the Xbox Series X and its controller for around 2 years now. (Probably past the warranty sadly.) I also have many other controllers with analog sticks on them. I've had a Nintendo Switch Pro Controller since 2019. After 3 months of use, the right stick got drift. After another 4 months of use, the left stick is starting to drift and at the horizontal axis's are both dropping inputs and doing a weird drift to a diagonal. The Nintendo Switch Pro Controller I have only has light stick drift that doesn't affect gameplay. I tried every easy tutorial out there and concluded that it's a hardware problem. And yes, I did try updating it. TWICE actually. There's a bunch of 3D games I look forward to playing and most of them don't support Nintendo controllers. (Sorry for the constant Nintendo references, it's the only competitor console I actively associate with.) If there's some way I could get this problem fixed for cheap I would be grateful, I really want to believe that Microsoft is trying their best and this is making me doubt that.
