Entity Framework 6 and SQL Server 2022 can't connect - entity-framework

Question

I have a trivial console app and I can't connect my DBContext (Entity Framework 6.0.0) to the SQL Server 2022 database.
public class TestContext : DbContext
{
public TestContext(string connectionString) :base(connectionString)
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
}
}
Connecting with SqlConnection works just fine, but EF6 doesn't. There's no error.
static void Main(string[] args)
{
SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder();
cb.DataSource = #"***";
cb.InitialCatalog = #"EF6Test";
cb.IntegratedSecurity = true;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = cb.ConnectionString;
conn.Open(); //connection OK.
try
{
using (var ctx = new TestContext(cb.ConnectionString))
{
var s = ctx.Database.Connection.State;
;
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
When I add a breakpoint, the only error is here:
Edit: this is my App.config:
