It's astonishing that this has happened 5 times. From the rest of your description, especially the fact that the camera will not power on when connected to the floodlight base, I guess I'd wonder whether the problem is not in the camera itself, but in the base unit that contains the floodlight.
I understand you're an electrician, but are you certain there is nothing about the wiring of your second floodlight that would prevent power from reaching the floodlight base unit?
There are numerous other posts in this forum from customers who are getting low battery warnings from their floodlight cameras. Since they are hard-wired, that simply shouldn't happen. We've had a battery camera for 18 months, plugged in with the optional power cable, and the battery has remained charged--as expected. Floodlight camera customers also report their cameras going offline, and their floodlight component not working. Perhaps there are defects in the floodlight base unit that can prevent power from reaching the camera, as well as defects that can prevent power from reaching the floodlight component, and that's what you are encountering.
Sorry for all the theorizing. None of the replies in this forum from Google Nest staff have shed any light at all on why so many floodlight cameras have problems.
Good luck with your 6th camera.
