It’s working fine with Multistep form, Already tested with Multistep form, Please check gravity form version, WordPress Version, It may be due to some of you other plugin code. Please check this by keeping only active this plugins or in activating on other site.
Hope you resolved the problem.

Updated js code on plugin for triggering after second render.
jQuery(document).on(‘gform_post_render’, function(event, form_id, current_page){
jQuery(“.swe_gf_phone_with_country_code”).intlTelInput();
});
