I am using Folia and need to load a world that has already been saved to disk. However, I’m unsure which scheduler to use: EntityScheduler, GlobalRegionScheduler, RegionScheduler, or perhaps no scheduler at all

Code for loading the world:

WorldCreator worldCreator = new WorldCreator("world");
worldCreator.environment(World.Environment.NORMAL);
worldCreator.generateStructures(true);
worldCreator.type(WorldType.NORMAL);
Bukkit.createWorld(worldCreator);

The error thrown when running the code：
