I know how frustrating it can be. And happy to help....unfortunately. When I asked to see the other side of the board, I was hoping to see how you had everything wired. Looks like you flipped switch wiring to the other side of the board.
Next time you are fully wired up, include pics of both sides...I am probably missing something but was confused when you talked about jumping act and aux. you want one pin of each switch going to the ground....bigger pad under all the accent led pads (4th one in after the 3 tiny ones) and the other pin from each switch going to the act and aux pads in the middle. I know you mentioned testing but always good to test continuity on switches with your multimeter before attaching to the board.
Lastly. Since we are talking about switches, not sure what your saber is, but make sure you don’t have any shorts on the switch side (for instance, if the solder could hit the ousted of the hilt or something underneath.
Apologies if I missed this info/detail previously, just a bit of a moving target in the thread.
