Run C# .NET Framework (x86): try-catch causes SharpLab to become a blank page

[AndreasLeeb]

Problem

When the undermentioned code snippet is run, you get a blank page (empty <main> tag). Happens with latest Firefox, Chrome and Edge. The try-catch in the code seems to cause this issue, as it only occurs when I add the try-catch clause.

Steps to reproduce

• Open a fresh sharplab.io page
• Set the platform to .NET Framework (x86)
• Set Results to Run
• Paste the following source code:

using System;

X.Ev += () => throw new Exception();
X.Run();

public class X {
    public static event Action Ev;
    
    public static void Run() {
        try {
            Ev?.Invoke();
        } catch { }
        Console.WriteLine("Hello");
    }
}
