ADRV9361-Z7035 failure

I have a custom carrier card that holds multiple ADRV9361s and one of the ADRV9361 boards suddenly stopped working after around 6 months of use.  Upon power up, the config done LED will blink rapidly (~4Hz) and VCCIO_EN is never enabled.  Probing deeper into the issue, I have discovered that a failure seems to have occurred somewhere on the SOM causing a short of the internal power rail VCCPCOM-1P8V to GND (~0.2 ohm). Does anyone have any experience with this particular failure mode?
