无法在设计师中打开Windowsform

Question

从 NetFramework 4.5 迁移到 .Net 5.0 后，我的 WindowsForm 无法在设计器中打开。

输出如下：

Microsoft.DotNet.DesignTools.Client.Host.ServerProcess.d__30.MoveNext()
    
    System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
     
    System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
     
    Microsoft.DotNet.DesignTools.Client.Host.ServerProcess.d__25.MoveNext()

    System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
    
    Microsoft.DotNet.DesignTools.Client.DesignToolsClientLoader.d__26.MoveNext()  
 

我还查看了 Microsoft 应用程序事件管理器，发现：

 Application: DesignToolsServer.exe
    CoreCLR Version: 5.0.1522.11506
    .NET Version: 5.0.15
    Description: The process was terminated due to an unhandled exception.

       at DesignToolsServerX64.Program.Main(String[] args)
    
And this error  too :

 DesignToolsServer.exe

我应该如何将我的 WindowsForm 从 .NetFramework 4.5 和 32 位设计器迁移到 .Net5.0 和 64 位设计器？有可能吗？
