does anybody know what is going on when a specific ESC in a 4-in-1 just fails? no physical damage, warning or anything! it just refuses to work

Maybe a defective MOSFET on the board? Did you check it with the configurator? Can it still read all 4 escs?

I am a drone dev, and like 95% of ESC failures I've encountered were from knockoff or under-spec'd capacitors. Even a brief power-up with motors connected can cause damage (I have seen an ESC die from a Dshot beep) if you don't have a proper capacitor, and the ESC does not have TVS diodes for emergency protection. Sometimes it's one channel, sometimes the whole ESC fails.
Depending on how and when it fails, it can burn to a crisp (including half the drone) or show absolutely no visible damage whatsoever.
Also, check your wiring, and all the pins inside the connector (if it's solderless), one bad solder joint or a bent pin inside a connector might take down a single ESC channel.
