I have tested all the traces that connect to the trigger assembly and confirmed that they have connectivity. I have cleaned the flex cable multiple times. I have also ordered a replacement part and the same problem still resides. There are no other issues with the controller. Any ideas as to what could be wrong?
Is this a good question?

I have had this happen with my Nintendo Switch Pro controllers before as well. The first step is to take the back plate of the controller off, open it up, and carefully lift the triggers and rubber pads up. If you see any debris, or corrosion, use some isopropyl alcohol on a q-tip to gently wipe it off of the contact. If this still doesn't work, you may need to get a new controller, unless you're willing to replace the internal board.
