Hi everyone, this is my first post here and hoping someone can help me with this problem.
I hope this is the right place to post this topic.
So a little backstory, I was installing Mill Max Hotswap Sockets on my Keychron K4. Managed to tore the PCB traces here and there. Resulting 3 whole rows of the keyboard stopped working. I googled a lot of things online on how to repair PCBs, and managed to fix 2 whole rows by creating bridges between the row pins with wires. But this last row just won't work even though the connection between the pins are fine (I tested it with a multimeter).
Here's some images to help with the story

I've also tested the connection between the column pins (yellow lines) to each correspond nodes and it's also fine.
I apologize in advance for the bad soldering job, I'm a mess
I've also tested the connection between the nodes and it shows no problem.
Here's a video of me testing the pins :

This is my first time troubleshooting a PCB so I don't have that much knowledge on PCBs.
I'm assuming the problem is somewhere within the PCB itself rather than the switch pins? Any ideas?
If you need any other images or information pls let me know, thanks in advance!
