I started playing in my hardcore world. When it's time to fight the dragon. A problem occured. There is no stronghold in my world.

As I mentioned before, there was no stronghold in my world, out of curiosity I entered the same seed on the creative one and nowhere could I find a stonghold, or the previous command (/ locate minecraft: stronghold or an end pearl (she didn't even want to come out). Then I entered. on a random world on the same snapshot And there was no stronghold anywhere, please help.
