C# Winform一开始就报错System.Reflection.TargetInvocationException

[Helloworld3020]

各位大佬，

研究好几天了没找到原因，还请大佬们帮忙看看。

C# winform程序在使用过程中没有更改程序代码的情况下，重新开始运行后突然在program.cs程序中报错，之后就一直这样了，重启电脑也没有用，问题出现前的使用过程中存在用VS同时开启两个名称都叫Pannel的winform程序，但是没有改过代码。

static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Pannel());（报错处）
}
}

报错截图:


详细报错信息如下：

引用 1 楼 icoolno1 的回复:

Application.Run(new Pannel());这地方只能是个Form或Form的子类，你这个Pannel是什么？

这个Pannel就是Form，只是改了个名字而已。

再补充一下，同样的代码，放到其他的电脑有时候是可以运行的，但在我的电脑上跑就一直有问题。

把异常设置的选项都勾选上 别有事没事 try catch 错误的地方根本不在这 在form里面

This exception was originally thrown at this call stack: System.Diagnostics.Process.Start() System.Diagnostics.Process.Start(System.Diagnostics.ProcessStartInfo) Panel.Pannel.Programming() in Pannel.cs Panel.Pannel.btnStart_Click(object, System.EventArgs) in Pannel.cs System.Runtime.CompilerServices.AsyncMethodBuilderCore.ThrowAsync.AnonymousMethod__6_0(object) 你是不是点击了按钮 才报的错???

按钮事件里启动另一个进程，但找不到可执行文件。

最后提示“ 尚未提供文件名,因此无法启动进程” ,是不是启动文件路径不对，或者配置错误
