Aston Martin Db11 won't start after dead battery recharge
Discussion
first pic shows what looks to be a passenger side air bag malfunction. OTOH if a low voltage battery is the problem, IME just about any fault code could be generated.
and BTW, for a number of years now that engine computers will not even attempt to turn the engine over if sufficient voltage (and they are the arbiters of what is sufficient and what is not) is not present.
i would either get a new battery or use a known battery in good condition, disconnect the battery cables in the car, connect up the new (or known-to-be-good-one) and see what happens. it would always be my first step in any car manufactured in the past 20 years.
even the engine computer in my 2001 dodge ram pickup won't even send any current to the starter motor if there is insufficient voltage detected.

I had a starting problem after my battery failed on my 2012 V12 Vantage. I tried everything, battery charger, jump starting and even a new battery. I had the car transported to the dealer and they scanned the system and found that the throttle bodies were disabled. They reset them and the car started just fine. You may have the same problem.

Try a hard reset. Remove the battery + connection and earth it for a couple of minutes. Then reconnect and wait for 5 min, then switch on ignition and wait a few minutes more. The systems may well reset for you. You may lose some less critical stored functions and settings which will need to be recovered, such as seat memory etc.

They won't cause a DB11 to not start, one is the airbag, the other is a bulb failure.
Are you getting the red ring on the start button when you press the brake pedal? Are the brake lights coming on?
Are you getting a massive voltage drop at the battery when you try and start it?

Red ring yes. Battery tender and charger says fully charged.
My car had a similar issue at the time of a completely flat battery.
It turned out to be a fuse for the starter circuit. The other messages will probably be flat battery related but not your chief culprit. They should be easy enough to sort if the case.
Mines an older Vantage so quite different probably but I see no reason that this isn't similar.
My handbook showed the fuse number and location.
