There are several possible reasons why this may happen but without knowing the recipe or how you made the dough, it's hard to tell what went wrong.
Normally, you allow the dough to roughly double in bulk, knock it back, form your loaf and then let it rise again before baking.
It is possible to over-prove a loaf which causes the internal structure to disintegrate and lose the trapped gasses which would expand in the hot oven and cause the loaf to rise.
Add some vitamin C to the flour, a crushed up tablet will do, and this will strengthen the gluten, which is what forms the structure of the loaf.
Possibly your oven is not hot enough: I would use a minimum temp of 220 deg C for the first 20 mins of baking the loaf; then reduce to 200 C till cooked. But oven temperatures need to be measured; the thermostat is often not accurate. My top oven runs 30 deg C cooler than indicated, so I have to adjust it. An oven thermometer costs around £5 and is a worthwhile investment.
Whilst heating the oven, keep a baking sheet on the shelf and then put your loaf, on its own tray, onto this. The immediate heat transfer will help the rise.
The time of baking needs to be 35 min upwards for a 1 Kg loaf: it's done when it sounds hollow if you rap it on the bottom.
Hopefully, some of these ideas will help for the next loaf.
I'd use this loaf to make a bread & butter pudding: it sounds to me as though it would be just right for that.
