Idk, there's possbily more stuff I missed, maybe some of the new mountains, cliffs, or caves won't spawn either. Maybe I need to upgrade to Java 16. There is so much thing I might have missed. But if this is a real issue with 1.17, please fix it somewhere in the near future.
Thanks!
This is happening to me as well, and this bug was discovered 9 years ago? I was trying to play on the reccomended version of Forge 1.18.2 so I could play Cracker's WIther Storm Mod with the latest version of Flywheel for 1.18.2 as well. I create/join a world, and when it finishes that world loading screen saver of the world being generated it crashes and gives me the exit code -805306369 when the Launcher opens back up. Can someone, a moderator, PLEASE give options to fix this bug? I want it done as soon as possible so I can play Minecraft: Java Edition again.
