If debugging on Windows in IntelliJ via Image, no error log is provided inside the IntelliJ Debug console.

Steps to reproduce:

flutter create windows_debug_example
cd windows_debug_example

Add exception in build method:

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      debugShowCheckedModeBanner: false,
      home: const MyHomePage(title: 'Windows Exception Demo'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  final String title;

  const MyHomePage({super.key, required this.title});

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  @override
  Widget build(BuildContext context) {
    throw Exception('Exception in build method');
  }
}

flutter run -d windows -> Outputs the error into the console ✅ -> This is working as expected (but it doesn't work inside the Debug Window)

How it should be:
Clicking on the debug button should do the same in IntelliJ. ✅

How it is:
Clicking on the debug icon for Windows device in IntelliJ does not print the error in the console. ❌
