VS Code Breakpoints not working while debugging Azure Function

Question

I'm using VS Code on Windows 11, to debug my Python Azure Functions locally

When running the debugger I am prompted with the following (https://i.sstatic.net/4a65Y85L.png)

When I select the option,'Run Emulator' everything runs smoothly until the following error pops-up.(https://i.sstatic.net/Um5aDfNE.png) (Never seen this before)

At this point I can ignore the error and continue/execute my API. The code runs, but it does not stop at any of my breakpoints.

Another opservation: The debugger starts but it does not show the usual debug toolbar start/stop/continue/pause debugging actions.

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "myproject",
            "type": "debugpy",
            "request": "attach",
            "connect": {
                "port": 9091,
            },
            "preLaunchTask": "func: host start",
            "justMyCode": false
        }
    ]
}

host.json uses the extensionBundle version "[4.0.0, 5.0.0)"

local.settings.json

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "LOCAL_PORT": 7071,
    "AzureWebJobsStorage": "UseDevelopmentStorage=true"
  }
}

Azure Function Core Tools version : 4.2.2

install azurite (npm install -g azurite)

run azurite in to other terminal (azurite)

open local.settings.json file and change ("AzureWebJobsStorage": "UseDevelopmentStorage=true")
