There was too much water and too hot when the dough was mixed - flour appears to be cooked, like choux pastry - which implies the yeast died instantly and never leavened the bread.
Then there as a failed attempt to rescue the dough by addind more flour. There is a tentative crumb texture along the cut area.
And finally, the oven was too cold. Or, even worst, the bread was put in the oven at a low temperature or while it was heating to force the dough to rise.
That bread, and we are being very generous by refering to it as such, is dangerous to eat atop being an obvious disappointment. A bit of heart burn, if they were lucky, serious diarrhoea if not.
