我在尝试执行“Hello World！”时遇到运行时错误。来自 Suave 网页的程序：

打开 Suave.Web 打开 Suave.Successful

[<EntryPoint>]
let main argv =
    startWebServer defaultConfig (OK "Hello, Suave!")
    0

出现此错误：

$YoLo:.cctor 在'/Users/[myUserName]/Library/Mobile Documents/com~apple~CloudDocs/Projects/SuaveRestApi/SuaveRestApi/bin/Debug/Suave.pdb'。可能是格式错误的 PDB 文件。堆栈跟踪：

Visual Studio for Mac 和 Suave 似乎存在问题。我在 Visual Studio Code 中做了同样的测试（也适用于 mac）并且工作正常。
