      I tried to open my world from 21w19a in 21w20a, but i can't. Even though, it worked in 21w19a

      Note :

      • I Play In Minecraft Demo.
      • I Am Using The Negative Time Using The Ant Venom's Technique
      • I Add Two Datapack, The Latest Caves And Cliffs Preview Datapack (21w20a), And One Datapack That Worked In 21w19a.
      • When I Press Safe Mode, It Doesn't Load.
      • In The Datapack, There Are Some Template Pool, But Without The Structure
      • The Datapack Is In The Attachment.

       

      This Is The Game Output When I Tried To Open The World On 21w19a :
