Side buttons do not work

Hello all,

Yesterday, I was trying to swap the back housing of my iPhone 13. While doing that, when I was removing the buttons (Power, volume buttons connector) connector from the board, I have a feeling that my plastic repair tool (the one people use to disconnect the cable) perhaps damaged/scratched the connector. Anyway, after putting it all back together, none of my side buttons worked. I had an extra button cable and that one, the power button on the right side worked, but still no luck for the left side where the mute and volume buttons are located.

Does it mean I may have damaged the cable connector on the board where I plug the connector in? If so, how can I replace it? This seems like replacing the entire board?

Can someone help me how to troubleshoot this? Thank you
