Steam uninstalls ETS2 twice within a week without valid reason

[AI_Compre]

Hi everyone, I think this problem is caused by missing or corrupted appmanifest_227300.acf and appmanifest_270880.acf files,The actual game files are not lost in any way
大家好，这个问题，我认为是 appmanifest_227300.acf 和 appmanifest_270880.acf 文件丢失或损坏造成的，实际游戏文件并没有任何丢失

These files are located under: Steam\steamapps folder or SteamLibrary\steamapps folder
这些文件位于：Steam\steamapps 文件夹或 SteamLibrary\steamapps 文件夹下面

What I observed under some live streams in Simplified Chinese, when the acf file was lost or corrupted, the Steam program just repaired or redownloaded the acf file
我在一些简体中文的直播下观察到的，当 acf 文件丢失或损坏的时候，Steam 程序只是修复或重新下载了 acf 文件

I think the problem may be caused by an error in some part, such as hard drive SMART or something else
我想这个问题可能是某部分出错造成的，例如硬盘 SMART 或者其他
