Can desoldering and soldering to replace a capacitor which is part of an RC filter of an I/O pin cause that pin to develop an internal short to VCC?

This problem has now happened on 14 PCBAs. Any insight would be gratly appreciated.

Let's say it would surprise me, more likely solder reflow or esd.

Perhaps protect the chip more during the process, and be very quick. Use an ESD safe soldering station, and make sure that's working properly.

Look at the solder mask, and how much the board house shrunk that back, and what other things are in the proximity of the part changed, and that the capacitor part itself is not defective.

I have done this many many times and never developed an internal short to ground on a pin. I would look into your process and how the rework is being done.
