First time building a keyboard. I'm not good at it. About 6 keys don't work. How do I troubleshoot/debug this?

Trying to build my first keyboard and I'm not having much luck haha.

It's my first time soldering so sorry for the eye torture.
It's a Quefrency board (https://keeb.io/collections/frontpage/p ... 2980861022) and I had to solder the diodes and micro controller on myself. I elected to use the Elite-C micro controller but it seems to be mostly the same as the Pro Micro.
After soldering it on and flashing the firmware the 2, W, S, and Z keys don't work (I'm only concerned with this left half of the keyboard currently).
- I tried desoldering these to see if it was the switches, but even if I use tweezers I can't get the keypress to go through.
- I've also tried reflashing the firmware multiple times.
- I used a multimeter to check the continuity with these tweezers and it indeed appears to work.
- I used the same multimeter in diode mode to check all the diodes on the board and they all read the same, around "750".
This is making me think it's the micro controller or the PCB. Maybe I got it too hot or something during soldering?
I took some pictures, is there anything that looks weird? https://imgur.com/a/ga6emUs Should I buy a new PCB or micro controller (is there a way to test if these are at fault)? Is it the soldering points? They all look shiny and appear to make contact with the pads.
