c#保存设置失败:配置文件已被其他程序更改

我刚刚发布了一个程序(OptiKey)，它传递用于在单个类中获取，设置和保存用户设置的lambdas:

lambda从这个类传递(从第143行开始):https://github.com/JuliusSweetland/OptiKey/blob/master/src/App.xaml.cs

到这个类:https://github.com/JuliusSweetland/OptiKey/blob/master/src/Services/WindowManipulationService.cs

注意:"set" lambda更新设置的值(例如:Settings.Default.Whatever = X)，然后调用Settings.Default.Save()

我不能在本地复制崩溃，但我收到来自用户的崩溃报告，其中Save调用抛出异常，我通过从磁盘重新加载设置来捕获和处理，然后再次尝试保存。这不起作用，重试也会抛出异常。

有人告诉我，即使用户不使用病毒扫描程序(我认为这可能会锁定用户)，也会发生这种情况。设置文件)。

任何想法?这是我遇到的导致崩溃的最大原因，我不知道如何重现它!

仅供参考，设置也可以在代码中的其他几个地方访问(get/set+save) -可能同时，但我不认为这会发生。
