Thank you very much for your efforts, Babiz80, but I checked or did all this already. Btw, I'm below the 60 secs that you think is ok. I do not. I don't understand why it's too much to ask that you can just turn on a simple player and start using it immediately. I understand it technically given this firmware/software design but I don't see why such devices need to be programmed so inefficiently. My Sony camera can do gigantically more and is instantly there when I switch it on.
Well, the first problem is that it is not a simple player.
It has to handle 256GB - 1+ TB of music database, scan/modify/create a database, so the user will not swear because the database is not accurate, prepare the Android environment, which has to handle the 1001+ features, updates, synchronizations, initialize/check/sync all the processes and apps that need to start up, prepare and scan all the wifi, Bluetooth settings/users/environments, and on and on and on, and on.
The CPU basically runs flat out at 100% to initialize and start up the environment. All done in a burst, so that the user will be disturbed as little as possible, and will have a perfect setup every time. All they have to do is press a button to start the process, and wait a bit. Everything that is done probably uses 1000+ times more processing power than the computers that handled the Apollo mission to the moon in the '60s.
Yes, it would be great if it could be done instantaneously, in under 1 sec. But not possible with today's technology.
Could we ask that users start the boot of the device first thing, before they go to the washroom, get a glass of water/coffee, check their mail. By the time they look at the DAP, it will have "magically" finished it's startup, and be waiting patiently to serve you?
More directly to your request, there are DAPs that start up almost instantly. I have had, and still have some. In general, they are exactly what you are asking for, a simple player that just plays music. AND VERY LITTLE ELSE.
- The simplest had no wifi or bluetooth, limited to 128GB microSD card (FAT32 only), no touch screen, a very simple User Interface, etc. Firmware updates are done using a small microSD card formatted a certain way. Music was on a slightly larger microSD card formatted another way. The UI (User Interface) was definitely not sophisticated. The controls required that you get used to them, as that was the only option. No APP Store, and absolutely no streaming. Don't even think of Youtube.
Some of these players rewarded you with "music", for which you forgave them all their unfriendliness, lack of options, etc., etc.
Unfortunately, not all were musical, in spite of all the drawbacks that you had to put up with.
So you do have a choice. Pick one of the SIMPLE players, and you can get a short, almost instantaneous startup.
Or leave the Sony on all the time, and there is no startup delay. In fact, many users of the 1st gen WM1A/Z left them on for months/years without ever shutting them off, unless they were doing a FW update, or just doing a periodic restart to clean up the crap that builds up in the OS over time.
The Sony is a modern, sophisticated machine that is stable, and sounds very good. The minute that it takes to start up? Would be nice if it were shorter. But you can work around that. The payback is that it plays music very well.
In any case, about the long startup, in the immortal words of Bart Simpson: "Don't have a cow, man"

Now I'm under messing up with adb, first making backup of allowed thing downloadable from walkman, then I try to lear about remove some android component, do some trial and error and of coure if I discover sometimes of interesting thing about change regional code on nw-a306, I'll post here.
You can also leave walkman still powered on and keep connected to usb charger when nit used is another approach... But android os is very hunger of power because trought years is evolved to give all security standars needed by globalization's. All is done not for great user experience indeed is a way to protect industrial rights in world market.
