Ring floodlight cam suddenly not reconnecting to Wi-Fi or entering setup mode

I have 10 devices, 9 without issues. However, recently, one of my wired floodlight cams would not reconnect to Wi-Fi, nor will it enter setup mode. I have extensively tried every step detailed in troubleshooting guides and in the app to no avail. As of today, the device will not enter setup mode at all (the light will not flash) even after power is cut off, the device reset, and even if it is removed then attempted to re-add to the app, nothing works. I have a feeling this unit is essentially bricked. What options do I have as far as further investigation and/or replacement (if that is even on the table). I have already replaced the unit itself with a new one (which connected immediately without issue), but I feel that having a dead unit without knowing what happened or why it won’t connect is troubling. Thanks in advance.
