More kneeding is wanted to improve the texture, let it rest for a couple of hours and go back at it for 5 mins, leave it for a couple of hours and give it another 5mins. Then shape it in to a loaf and drop it into your tin and leave to prove until its ready.
Doughy texture means to much water or not long enough in the oven, looking at your crust i would say it needs to go lower in the oven and as high as it will go temperature wise
For the no kneed bread I dont kneed at all . All i do is mix the ingrediants, leave for 24 hours, then just fold it over 3 times over its self, then leave for 10mins, then shape it and leave for an hour, and cook . Done
In my kitchen in this weather, about 35-45 mins. It can take an hour if it's not as warm
