楼主我也遇到了你这个问题，如果你用的是windows server 2012 版本的话可以换一个高版本的系统试一下，我用的是windows server 2022，下面是我的分析
通过看日志发现
第一处：
[2024-11-10 02:40:58] Downloading manifest: https://client-update.steamstatic.com/steam_cmd_win32
第二处：
[2024-11-10 02:40:58] Error: System OS version is not compatible with package manifest OS type
这两个日志大概意思如下：
第一处会下载一个清单，通过编辑器打开后发现
====================
"win32"
{
"version""1733269577"
"ostype""win10"
"steamcmd_public_all"
====================
我发现这个win10有点可疑，可能2012使用的是类似win8的ostype（个人猜的），所以导致这个系统清单与系统版本不符这个问题，然后抛出了异常，至于为什么最后会出现
====================
[2024-11-10 02:40:58] Error: System OS version is not compatible with package manifest OS type
====================
我怀疑应该是异常抛出后代码去执行其他的操作,但是因为没有更新完导致文件不全(有可能是代码抛异常抛错了)
总结一下:应该是steamcmd不再支持windows server 2012这个系统,但是官网也没有说,我一开始也被这个最后一行的问题搜了半天,都没有结果...
