The only way to stop it for appearing is restarting Godot.

### Steps to reproduce

1. Execute a C# script with an error
2. Select the error in the Debugger/Errors menu
3. Click "run project"

### Minimal reproduction project

Example code with error:

```csharp
using Godot;
using System;

public partial class ErrorTest : Node 
{
    public override void _Ready() 
    {
        Node nullNode = null;

        nullNode.ToString();
    }
}


```

			cpp_cond->set_text_alignment(0, HORIZONTAL_ALIGNMENT_LEFT);
			tooltip += vformat(TTR("%s Error:"), source_language_name) + " " + oe.error + "\n";
