That is just a decoupling Capacitor on the Analog voltage rail. It's value is around 100nF, but you can just leave it off, it will not hurt anything at all with it missing.

Thank you for your answer. My character moves by itself when I play, I change the joystick twice, but I still have the same problem, I told myself that it could come from this component that I can be removed without paying attention.

That Capacitor could not cause that issue.

Moves by itself how exactly? and in what direction/s?

Moves fast, like stick is pressed all the way?

Moves slowly, aka drifts, like it is barely being pressed?

Moves randomly on it's own?

My character advances very slowly even if I don't touch the joystick, do you have an idea?

It's because of the calibration of the old stick to the controller versus how the new one is. You might go thru 10 sticks or more before you found one that worked  good enough. There are several ways to get it working right again.

Indeed, after having put the 100nF capacitor back in place, I still have the same problem. Is the card just double-sided or multilayer?
I saw that a missing patch was missing on one of the sticks of the joystick. thank you

That board is 4 layers. https://www.acidmods.com/forum/index.php/topic,44645.0.html

A slight drift has nothing to do with anything missing. The controller is calibrated after it is made with the sticks that it was made with. Replacing a stick can cause a little bit of drift, because no two of them are exactly the same.
