进度：已成功更改旧版本文件

虽然原因还不知道，不过我通过以下具体步骤修复了问题

• "未找到 ID 为[xxx]的内容块"：删除[笔记本名称].siyuan\filetree.json 文件，关闭思源笔记程序后重新打开，之后可以正常打开
• 部分.md 文件未成功转换成.sy 文件：文档树-对应的文件或文件夹右键选择“删除”-父级文件夹右键导入文件或文件夹，之后可以正常打开
  • 导入后我电脑上的[笔记本名称].siyuan\filetree.json 内未增加新导入的内容，逐一修改新导入的文件的文件名后 filetree.json 触发了更新，添加了相关文件的内容

• 所有原日记内容打开.sy 时报错
• 做了一定隐私屏蔽处理，下面的文件不在 log 里：

另外发现路径“...笔记本名\AA\BB\CC\”下，“【BCG-TMI】抢滩私域新战场-2021 中国私域营销白皮书.md”这个 md 文件没有被转移成.sy 文件，而是被清除了。

目前试过的傻瓜操作有：

• 关闭笔记本并重新打开
• 关闭 siyuan 并重新打开
• 关闭电脑并重新打开
• 换一台没用装过 siyuan 1.1.83 的电脑安装 1.2.0-beta6 并从网盘复制 1.1.83 版本的文件到 data 文件夹并打开

以上方法都没有效果。。
