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"
4. A "Save Resource As" menu appears.

### 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();
    }
}


```
