When the document is ready, you can clone the contact form card, at this time, since you didn't select the country, so they will use the default country. We can use it as initial card. Then, after clicking the add card button, you can append the previous cloned card (initial card) to the container and use JQuery to get the last card (which is the initial card).

After modified, the code like this:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/intl-tel-input@17.0.8/build/css/intlTelInput.css">
 
<input type="button" id="add-another-contact-form" class="btn btn-primary" value="AddForm" />
<div id="contact-forms-container">
    <!--Contact Form-->
    <div class="form-card contact-form-card">
        <form>
            <div class="form-row align-items-center">
                <div class="col-md-6 mb-3">
                    <label for="">Phone number</label>
                    <input type="text" class="form-control contact-phone" id="contact-phone" placeholder="Phone number">
                </div>
                <div class="col-md-6 mb-3">
                    <label for="">Fax</label>
                    <input type="text" class="form-control fax-contact" id="fax-contact" placeholder="Fax">
                </div>
            </div>
        </form>
    </div>
</div>

JS scripts:

@section Scripts{
    <script src="https://cdn.jsdelivr.net/npm/intl-tel-input@17.0.8/build/js/intlTelInput.min.js"></script> 
    <script>
        $(document).ready(function () {
            var contactCounter = 2;
            //clone the first card, use it as the initial card.
            var clonedForm = cloneForm($(".contact-form-card:first")); 
            // Initialize the first form
            initializeForm($(".contact-form-card"));

            $("#add-another-contact-form").on("click", function () { 
                var newform = clonedForm;
                $("#contact-forms-container").append(newform);
                //clone the last card, as the initial card.
                clonedForm = cloneForm($(".contact-form-card:last"));
                initializeForm(newform);
                contactCounter++;
            });

            // Function to clone a form
            function cloneForm(originalForm) {
                const clonedForm = originalForm.clone();

                const formTitle = clonedForm.find(".form-title");
                formTitle.text(`Contact ${contactCounter}`);

                const removeButton = clonedForm.find(".remove-form-button");
                removeButton.on("click", function () {
                    clonedForm.remove();
                });

                return clonedForm;
            }


            // Function to initialize a form
            function initializeForm(form) {
                const phoneInput = form.find(".form-control.contact-phone");
                const faxInput = form.find(".form-control.fax-contact");

                console.log('Check if the phoneInput element is correctly selected')
                console.log(phoneInput);
                console.log(faxInput);

                ////// Destroy previous instances if any
                //phoneInput.intlTelInput("destroy");
                //faxInput.intlTelInput("destroy");

                var precontact = intlTelInput(phoneInput[0]).destroy();
                var prefax = intlTelInput(faxInput[0]).destroy();

                // Initialize IntlTelInput for phone and fax inputs
                var itiContact = window.intlTelInput(phoneInput[0], { 
                    formatOnDisplay: true,
                    separateDialCode: true,
                    hiddenInput: "full_number",
                    utilsScript: "https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/17.0.8/js/utils.js"
                }); 
                var itiFax = window.intlTelInput(faxInput[0], {
                    formatOnDisplay: true, 
                    separateDialCode: true,
                    hiddenInput: "full_number",
                    utilsScript: "https://cdnjs.cloudflare.com/ajax/libs/intl-tel-input/17.0.8/js/utils.js"
                });

                // Store the instances in the element's data for later access
                phoneInput.data("itiContact", itiContact);
                faxInput.data("itiFax", itiFax);

                itiContact.promise.then(function () {
                    phoneInput.trigger("countrychange");
                });

                itiFax.promise.then(function () {
                    faxInput.trigger("countrychange");
                });

                phoneInput.on("countrychange", function (event) {
                    var selectedCountryData = phoneInput.data("itiContact").getSelectedCountryData();
                    console.log(selectedCountryData);
                });

                faxInput.on("countrychange", function (event) {
                    var selectedCountryData = faxInput.data("itiFax").getSelectedCountryData();
                    console.log(selectedCountryData);
                });
            }
        });
    </script>
}

The output like this:
