view button not working after taking steam deck apart

I decided to open my steam deck as the bumpers were not registering or need more force to register. After I'm done with the repair, I went to the controller setting to see if all the buttons are still functioning. Everything else is fine except for the view button. I took it apart again to check and see if there was any debris or if I missed something but nothing. I cleaned everything with isopropyl alcohol just in case and still nothing. I'm at wits end here. Even if my press the view button hard. It doesn't register. Does anyone know what might be the caused? The view button was working before I took it apart.
