Cannot debug Unity project with Firebase Analytics in VSC

Question

I am having a problem when trying to use the debugger in visual studio code for my Unity project. I use Firebase Analytics in my project, and I am able to compile and run my app in the Unity Editor, as well as on iOS and Android devices. However when I try to use the debugger in VSC I get this error:

Exception has occurred.
System.IO.FileNotFoundException: Could not load the file 'Firebase.AppCheck'.

Easy

This happens at Firebase initialization, on line 3 of:

    void Start()
    {
        Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
            var dependencyStatus = task.Result;
            if (dependencyStatus == Firebase.DependencyStatus.Available)
            {
                // Create and hold a reference to your FirebaseApp,
                // where app is a Firebase.FirebaseApp property of your application class.
                firebaseApp = Firebase.FirebaseApp.DefaultInstance;

                // Set a flag here to indicate whether Firebase is ready to use by your app.
                firebaseReady = true;
                MyDebug.Log("Firebase Analytics Ready");
            }
            else
            {
                // Firebase Unity SDK is not safe to use here.
                firebaseReady = false;
                MyDebug.Log($"Could not resolve all Firebase dependencies: {dependencyStatus}");
            }
        });
    }

Note that I don't use Firebase AppCheck (at least not as far as I know :) ), only Analytics. The file Firebase.AppCheck does not exist anywhere on my drive, nor do I want to install it, If I can help it. As I said, it all works in my release workflow, it's just the debugger that gets stuck. Any ideas on how to fix, or is it a bug in one of the tools?

Tool versions (all very recent/latest):

Unity 2022.3.33f1
Unity for VSC 1.0.2
VSC 1.90.1
Firebase Analytics 12.0.0

I searched extensively for a solution but could not find it. I double checked my configuration of the Unity plugin for VSC, it looks OK.
