Chosen Solution

I was playing a game and was pressing and holding this button a lot. Suddenly, it stopped working. I ran the diagnose on Big Picture mode and when I pressed it really hard it was detected, which led me to believe the problem was with the button piece and not the “sensor”. I haven’t tried opening it yet. How can I fix it? Update (12/19/2021) I opened yesterday and can say for sure now it’s the button.

I’m thinking the only way to fix this now is to 3D print another piece

9 out of 10 times its the sensor, not the button itself. the only way youre going to fix it is by opening it.
