Azure Functions Core Tools version in VSCode when debugging incorrect and failing (Microsoft.Azure.WebJobs.Script.Grp)

I am having problems debugging my azure functions app in VSCode on a macbook. I have a functions v4 project that was created on my Windows machine and moved over to my mac. When I tried to run the function app with func start --csharp and it wouldn't run so I ran func --version and it said it was running on function v3. I did an npm global install for version 4 and it worked using the func start command. However, when I try to debug the project. I get the following info in the console:

Executing task: func host start 

Azure Functions Core Tools
Core Tools Version:       3.0.5682 Commit hash: N/A  (64-bit)
Function Runtime Version: 3.22.0.0

It then gives me the following error:

[2024-12-09T13:46:18.629Z] A host error has occurred during startup operation '208b4c31-f120-4954-8bf8-d4b306fc3f88'.

[2024-12-09T13:46:18.763Z] Object name: 'IServiceProvider'.

It seems as though the debugger is using Azure Functions Core Tools 3. How do I change this to version 4?

My app is an isolated function. Here is the local.settings.json

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
  },
  "Host": {
    "CORS": "*",

I found the problem. I installed an earlier version of the Azure Functions Core Tools a little while ago to get an older version of the app running which ran on functions v3. I was not able to do so, so I upgraded the app. When I tried to run it, it said version 3 was installed. So I ran npm install to install the latest version globally. When I shut down and started VSCode again I got an error message that said two versions of func cli were installed and gave me the option to delete the one from npm or the one from brew. I tried uninstalling and running each one separately but no luck. However I noticed when I uninstalled npm and ran brew, it said v3 was running, even though I had uninstalled it and reinstalled the new version. I also tried running brew upgrade azure-functions-core-tools and it still said v3 was running. When I uninstalled it it still said v3 was running.

When I ran brew unlink azure-functions-core-tools@3 and ran func -version it showed there was no func cli installed. I then ran brew install azure-functions-core-tools@4 and then it shows that v4 was running. When I hit F5 the debugger ran properly.
