为什么 OpenFileDialog 会冻结特定计算机上的 WinForms 应用程序？
我有一个 WinForms 应用程序部署到同一办公室的多台计算机上。直到本周一，办公室中的所有用户都没有问题地使用该应用程序，并使用 OpenFileDialog 选择要导入的文件。一台机器对其他应用程序进行了大量更新，现在当我们的应用程序尝试显示 OpenFileDialog 时会冻结。它显示 OpenFolderDialog 很好；虽然我没能尝试 SaveFileDialog。重复一遍，它上周工作正常，我们的应用程序没有更新，但本周它在一台机器上冻结，而它在办公室的所有其他机器上工作。
有问题的机器安装了另一个 .NET 应用程序，并且我验证了 OpenFileDialog 在另一个应用程序中打开没有问题。
关于为什么 OpenFileDialog 会在一台机器上冻结的任何想法？关于如何解决这个问题有什么想法吗？我们可以在不知道原因的情况下尝试重新安装，但我认为最好调查原因以防止再次发生。
I have a WinForms app deployed to multiple machines in the same office. Up until this Monday, all users in the office used the app without issue and used the OpenFileDialog to select files to import. One machine had lots of updates to other apps and now freezes when our app tries to show the OpenFileDialog. It shows the OpenFolderDialog fine; though I failed to try the SaveFileDialog. Just to repeat, it worked last week, our app was not updated, but it freezes on one machine this week whereas it works on all other machines in the office.
The machine in question has another .NET app installed and I verified the OpenFileDialog opens without issue in the other app.
Any ideas as to why the OpenFileDialog would freeze on one machine? Any ideas on how to fix this? We could try reinstalling without knowing the cause, but I figured it is better to investigate why to prevent it from happening again.

该计算机过去可能已连接到不再可用的网络资源。 OpenFileDialog 可能正在等待网络资源响应，这将需要几分钟时间才会超时。
This machine may have connected to a network resource in the past, which is no longer available. OpenFileDialog could be waiting for the network resource to respond, which will take several minutes to timeout.
