这是一个比较久远的问题（也似乎好像应该只有1.19.X会出现或者问题），这个问题一般出现在 删除了带有自创维度的模组之后 再次进入已被该模组加载过的存档 存档将无法进入 ，并显示以下警告：

即使点了安全模式也没有办法恢复你的存档喵呜——，不过还是有办法的，唔，先让我们先看看运行日志：

由日志可以看到 Failed to load level data or datapacks, can't proceed with server load（加载地图数据或数据包出错，游戏将无法继续加载），这个问题是因为......

这个问题是因为存档文件中有残留的维度数据，游戏仍尝试加载这些数据，但由于相关模组/数据包被删除，缺失维度相关代码，导致加载出错

——[DLEF]数据包加载错误修复 (Datapack Load Error Fix) - MC百科|最大的Minecraft中文MOD百科的  模组资料正文

从上面那篇文章可以看到，地图缺少了帕斯特之梦、暮色的内容，通过询问该存档的拥有者可以得到确认，在删除了这两个自带了维度的模组之后就没办法进入存档了。

解决方案：

• 让模组帮你删除数据

  [DLEF]数据包加载错误修复 (Datapack Load Error Fix) 是专门为此而诞生的模组，将其放入模组文件夹后打开游戏，进入你出现该问题的存档，该模组会自动帮你删除。

  
  

• 手动删除残余数据

  你可以使用NBT explorer软件打开你存档文件夹里的level.dat文件，找到Data下的WorldGenSettings下的dimensions，找到你删除模组对应名称的世界名，选中，Delete，然后大叫，告诉你的存档说存档你好了呜呼——。
