Local Azure Function startup uses wrong Azurite service address

Question

I am trying to run an Azure Function(.NET 6, HTTP Trigger) using Visual Studio 22 locally that uses Blob Storage. Azurite is installed and starting up automatically as service dependency in VS. I am operating under Windows 10.

Stream.DataLakeTransaction: azurite.cmd --location "\AppData\Local\.vstools\azurite" --debug "AppData\Local\.vstools\azurite\debug.log" --skipApiVersionCheck
{ProjectName}: Azurite Blob service is starting at http://127.0.0.1:10000
{ProjectName}: Azurite Blob service is successfully listening at http://127.0.0.1:10000
{ProjectName}: Azurite Queue service is starting at http://127.0.0.1:10001
{ProjectName}: Azurite Queue service is successfully listening at http://127.0.0.1:10001
{ProjectName}: Azurite Table service is starting at http://127.0.0.1:10002
I{ProjectName}: Azurite Table service is successfully listening at http://127.0.0.1:10002

On my local.settings.json file, I have the following configuration, "AzureWebJobsStorage": "UseDevelopmentStorage=true", which should resolve to the default Azurite addresses, like port 10000 for Blob service for instance. But what happens is, for some reason, the function is trying to access it at localhost:5016/ upon startup and fails because the service is not running on that port. I wonder where that port comes from, shouldn't that configuration resolve to the default address and make a connection with the running Azurite instance?

Other settings I have on local.settings.json include these(db connection strings disregarded):

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "FUNCTIONS_EXTENSION_VERSION": "~4",
  }
}

Here are the complete logs of running the function, it fails with an exception stating that it couldn't read from the Blob Storage Secret Repository.

I tried reinstalling VS, Azurite, Azure Core tools, running the function through command line to isolate VS, restarts, cleaning Azurite Temp data - none of that helped so far. Setting "AzureWebJobsSecretStorageType": "files" on local.settings.json makes the function accessible(it doesn't fail during startup), but a trigger ends up with the same error as above in the end.

Any help would be appreciated, I can provide more info if needed. Thanks in advance.
