I was playing a single player game of civ 6 on Prince, and as soon as I captured my first city, the Defeat screen came up. As far as I could tell, nobody was anywhere close to any of the victory conditions.
If I re-load the game, I dont lose if I dont capture the city, but as soon as I do, I lose.
What am I missing that Im not allowed to capture someone elses city?

Just happened to me too.
In my case, I triggered a religious victory for another player.
To explain, a religious victory requires all other civilizations to have more than 50% of your religion. Everyone had been "converted" except this last civilization. When I took their last city, the condition that all civilizations be "converted" came true.
