The raid bugs often happen when all the villagers died and they are not cheering, but I checked in everyone's house but no one was there, but even worse that the "Raid" only stays on the entire time that it was active. And so and the "Raid - Defeat" was not on our screens, but that the villagers were all gone by the raider mobs while the bar was fine.
There may be some villagers underground or hidden, maybe have a look in spectator.
