C# && C#DK - Language Service crash when applying hotreload changes

**Version Used**:
- commit id: a98cc863d0676c36c128332cc0e795f35426d57d

**Steps to Reproduce**:

reproduce it in C#DK requires patching specific VSDebugCore and dotnet-project-system-vscode changes and it's not easy to set up, please reach out to me offline if you want to see an exact reproduce. Or please advice on an alternative way to provide a minimal reproduce, like adding a test case somewhere to call APIs in the callstack.

Here's the .diff I want to apply in hotreload, which adds a new line to the while-loop function body
```csharp
// See https://aka.ms/new-console-template for more information
using System.ComponentModel;
using System.Diagnostics;

await Print();

async Task Print()
{
while (true)
{
>>>>>>>
Console.WriteLine($"Process ID: {Environment.ProcessId}");
======
<<<<<<<
Console.WriteLine($"Process ID: {Environment.ProcessId}");
var record = new MyRecords { Id = 32, Name = "Test" };
Console.WriteLine($"Record: {record.Id}, Name: {record.Name} - {record.GetType().Name}");
await Task.Delay(3000);
}
}

record class MyRecords
{
public int Id { get; init; }
public string Name { get; init; } = string.Empty;
}
```

And here's the complete stacktrace from language service
```
