No XP or Egg from Ender Dragon

Yesterday I respawned the Ender Dragon and got killed during the fight. I respawned in the Overworld and as I was going back to the End Dimension my game crashed. After I reloaded Minecraft and opened my world my character was already in the End Dimension wearing all their gear and the very same gear I dropped when I died was still on the ground, so everything got duplicated somehow. I continued the Dragon fight normally but after I defeated it there was no XP or egg. Now I can’t respawn the Dragon in my favorite world. Maybe you all should sell Dragon Eggs as an in-game item through the store because it seems like these sorts of problems aren’t uncommon when I looked for help with this issue
