myprofilepagecontrollertest code coverage issue when deploying community components

I am using this code I found on a forum that someone said worked for them, but it's still not working for me:

/**
 * An apex class that keeps updates of a portal user in sync with its corresponding contact.
   Guest users are never able to access this page.
 */
@IsTest public with sharing class MyProfilePageControllerTest {
    @IsTest(SeeAllData=true) static void testSetContactFields() {
        User u = [select title, firstname, lastname, email, phone, mobilephone, fax, street, city, state, postalcode, country
                           FROM User WHERE id =: UserInfo.getUserId()];
        
        Account acc = new Account(Name = 'Test Account');
        insert acc;
        
        Contact c = new Contact(AccountID = acc.Id);
        MyProfilePageController.setContactFields(c, u);
        System.assertEquals(c.firstname, u.firstname, 'firstname should have been set as the firstname of the user for the contact');
        System.assertEquals(c.lastname, u.lastname, 'lastname should have been set as the lastname of the user for the contact');
    }
    @IsTest(SeeAllData=true) static void testSave() {
        // Modify the test to query for a portal user that exists in your org
        List<User> existingPortalUsers = [SELECT id, profileId, userRoleId FROM User WHERE UserRoleId <> null AND UserType='CustomerSuccess'];
        if (existingPortalUsers.isEmpty()) {
            User currentUser = [select id, title, firstname, lastname, email, phone, mobilephone, fax, street, city, state, postalcode, country
                                FROM User WHERE id =: UserInfo.getUserId()];
            MyProfilePageController controller = new MyProfilePageController();
            System.assertEquals(currentUser.Id, controller.getUser().Id, 'Did not successfully load the current user');
            System.assert(controller.getIsEdit() == false, 'isEdit should default to false');
            controller.edit();
            System.assert(controller.getIsEdit() == true);
            controller.cancel();
            System.assert(controller.getIsEdit() == false);
            Account acc = new Account(Name = 'Test Account');
            insert acc;
            
            Contact c = new Contact(AccountID = acc.Id);
            
            c.LastName = 'TestContact';
            insert c;
            c.title = currentUser.title;
            c.firstname = currentUser.firstname;
            c.lastname = currentUser.lastname;
            c.email = currentUser.email;
            c.phone = currentUser.phone;
            c.mobilephone = currentUser.mobilephone;
            c.fax = currentUser.fax;
            c.mailingstreet = currentUser.street;
            c.mailingcity = currentUser.city;
            c.mailingstate = currentUser.state;
            c.mailingpostalcode = currentUser.postalcode;
            c.mailingcountry = currentUser.country;
            controller.save();
            System.assert(Page.ChangePassword.getUrl().equals(controller.changePassword().getUrl()));
        } else {
            User existingPortalUser = existingPortalUsers[0];
            String randFax = Math.rint(Math.random() * 1000) + '5551234';
            System.runAs(existingPortalUser) {
                MyProfilePageController controller = new MyProfilePageController();
                System.assertEquals(existingPortalUser.Id, controller.getUser().Id, 'Did not successfully load the current user');
                System.assert(controller.getIsEdit() == false, 'isEdit should default to false');
                controller.edit();
                System.assert(controller.getIsEdit() == true);
                controller.cancel();
                System.assert(controller.getIsEdit() == false);
                controller.getUser().Fax = randFax;
                controller.save();
                System.assert(controller.getIsEdit() == false);
            }
            // verify that the user and contact were updated
            existingPortalUser = [Select id, fax, Contact.Fax from User where id =: existingPortalUser.Id];
            System.assert(existingPortalUser.fax == randFax);
            System.assert(existingPortalUser.Contact.fax == randFax);
        }
    }
}

I have also tried deploying another site to trigger Salesforce to create the component and hopefully avoid any issues, but I still get the code coverge error. I think I need to update this code somehow to improve my code coverage to be able to deploy my community.

The Salesforce generate class currently is:

/**
 * An apex class that updates details of a portal user.
   Guest users are never able to access this page.
 */
@IsTest public with sharing class MyProfilePageControllerTest {
    @IsTest(SeeAllData=true) static void testSave() {
        // Modify the test to query for a portal user that exists in your org
        List<User> existingPortalUsers = [SELECT id, profileId, userRoleId FROM User WHERE UserRoleId <> null AND UserType='CustomerSuccess'];
        if (existingPortalUsers.isEmpty()) {
            User currentUser = [select id, title, firstname, lastname, email, phone, mobilephone, fax, street, city, state, postalcode, country
                                FROM User WHERE id =: UserInfo.getUserId()];
            MyProfilePageController controller = new MyProfilePageController();
            System.assertEquals(currentUser.Id, controller.getUser().Id, 'Did not successfully load the current user');
            System.assert(controller.getIsEdit() == false, 'isEdit should default to false');
            controller.edit();
            System.assert(controller.getIsEdit() == true);
            controller.cancel();
            System.assert(controller.getIsEdit() == false);
            System.assert(Page.ChangePassword.getUrl().equals(controller.changePassword().getUrl()));
            String randFax = Math.rint(Math.random() * 1000) + '5551234';
            controller.getUser().Fax = randFax;
            controller.save();
            System.assert(controller.getIsEdit() == false);
            currentUser = [Select id, fax from User where id =: currentUser.Id];
            System.assert(currentUser.fax == randFax);
        } else {
            User existingPortalUser = existingPortalUsers[0];
            String randFax = Math.rint(Math.random() * 1000) + '5551234';
            System.runAs(existingPortalUser) {
                MyProfilePageController controller = new MyProfilePageController();
                System.assertEquals(existingPortalUser.Id, controller.getUser().Id, 'Did not successfully load the current user');
                System.assert(controller.getIsEdit() == false, 'isEdit should default to false');
                controller.edit();
                System.assert(controller.getIsEdit() == true);
                controller.cancel();
                System.assert(controller.getIsEdit() == false);
                controller.getUser().Fax = randFax;
                controller.save();
                System.assert(controller.getIsEdit() == false);
            }
            // verify that the user was updated
            existingPortalUser = [Select id, fax from User where id =: existingPortalUser.Id];
            System.assert(existingPortalUser.fax == randFax);
        }
    }
}

Happy to provide any further details. All help is appreciated!
