Same issue. I have bedrock realms. Survival and Hard Mode. I had defeated ender dragon years ago, probably 1.18 maybe 1.17. went to end today on 1.20.62 and went to my singular end portal, as I had only defeated the original ender dragon, and it teleported me to a few blocks away from overworld end portal instead of the outlying end portal as expected. I respawned the ender dragon and defeated him. It generated a new end portal 20 blocks from my original end portal. The original end portal goes to the overworld gateway. The new portal spawns to an outlying island end portal as expected. Obviously respawning the ender dragon isn't a fix but a work around.
