Thumb keys quit working after shock

I forgot to ground myself last night and as soon as I touched one of the thumb keys, I shocked the keyboard and the three thumbs quit working. The rest of the keys seemed to work but I didn't test all of them.

Today I tried flashing back to stock firmware, and this is what my nano shows now. My nano is from 2023.

I didn't solder this myself, so I don't have any tools to check connections.
