在查找Java时，若有空驱动器将丢出异常

[Orange-Icepop]

如题，使用MinecraftLaunch中的JavaFetcher.FetchAsync()（及其非异步方法）时，若当前系统中存在空驱动器（例如，未连接的网络挂载，某些拓展坞的占位USB驱动器），则会在该方法中抛出异常。经调用堆栈追踪与源码分析，发现是由于在文件系统中递归搜索java程序时未处理该种情况导致的。
平台：Windows 11 23H2 x64
包版本：3.0.7
恕无法提供截图。

抱歉我们最近有些忙没看qwq
不过马上开始修（

JavaFetcher.FetchAsync()已经有了一个检查空驱动器的检查，目前我们还不知道Bug产生的原因，可以提供一下这个异常的具体信息吗？最好附带一个堆栈信息以供分析🤔

好的，IDE显示的最终问题是System.IO.IOException:“找不到网络路径。 : 'Z:'”。我将一个SMB共享挂载到了Z盘，在运行该程序时目标服务器是关闭的。尽管是不同的应用程序，但是这个问题和我去年十月份遇到的报错信息完全一致。
以下是详细的调用堆栈：
