stuck button on midi fighter 3d

One of the buttons on my mf3d sticks and sometimes holds notes after I let go. I don’t want to remove the rubber feet if I don’t have to. In other words does any body have a fix that doesn’t include opening the controller’s housing?

I had a similar issue. I bought a second hand 3d and one of the buttons did not return after press. It got stuck sometimes.
I fixed the issue by applying some contact cleaner between the button and the hole.
