Thanks. I didn't notice any clearly called-out steps in article itself that were able to resolve my situation, since the "Programmer" utility wouldn't recognize the dongle and I don't have a $400 programmer. However, in the comments section I did just find the below nugget regarding the "Connect BLE" Utility and it somehow allowed me to recover the device.

The nRF Connect Programmer will not destroy your dongle. But you need to re-flash it with the connectivity firmware that is used by pc-ble-driver. The easiest way to do this is to press the reset button so that it enters DFU mode, and then select the dongle in nRF Connect BLE. When you do it will ask you if it should flash the connectivity firmware.
