Google.Apis.Auth 1.46.0.0 is installed but then being asked for multiple versions

I am able to get Firestore access through winforms by itself and it works. however, if I try to access Firestore through an external command, I get an error:

System.IO.FileNotFoundException: 'Could not load file or assembly 'Google.Apis.Auth, Version=1.44.1.0, Culture=neutral, PublicKeyToken=XXXXXXXXXX' or one of its dependencies. The system cannot find the file specified.'

The weird part is that I have Google.Apis.Auth, Version=1.46.0.0 as a reference.

If I change my reference version to 1.44.1.0, then it asks me to change the reference version to 1.21.0.0

How can I make this work?

Here is my code:

Notice that you set the environment variable for authentication and create the Firestore client (FirestoreDb db = FirestoreDb.Create("myProjectId");) within the method when the button is clicked.

        private void button1_Click(object sender, EventArgs e)
        {

            string path = "\\\\Mac\\Home\\Desktop\\testformsFirestore\\testFormsFirestore\\bin\\Debug\\myProjectJsonPath.json";
            Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", path);
            
            FirestoreDb db = FirestoreDb.Create("myProjectId");

            CollectionReference collection = db.Collection("Users");

Set the environment variable:

string path = "\\\\Mac\\Home\\Desktop\\testformsFirestore\\testFormsFirestore\\bin\\Debug\\myProjectJsonPath.json";
Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", path)

and make the initialization of the client:

FirestoreDb db = FirestoreDb.Create("myProjectId");
CollectionReference collection = db.Collection("Users");

in a previous step within your application.
