Advancement Corruption
An advancement fails to load, usually from a datapack. Its JSON is invalid or references something that does not exist, so Minecraft rejects that advancement.
このエラーはどういう意味ですか？
Advancements are data-driven JSON, often added by datapacks. 'Failed to load advancement' means a file is malformed, references an unknown trigger/criterion, or targets the wrong format, so it cannot be parsed.
