• Open …/wp-content/plugins/contact-form-7-multilingual/classes/shortcodes.php file.
• Look for line 21.
• Replace:

  	public function translate_shortcode_form_id( $atts ) {
  		$form = null;
  
  		if ( ! empty( $atts['id'] ) ) {
  			$form = wpcf7_contact_form( (int) $atts['id'] );
  		}
  
  		if ( ! $form && ! empty( $atts['title'] ) ) {
  			$form = wpcf7_get_contact_form_by_title( trim( $atts['title'] ) );
  			unset( $atts['title'] );
  		}
  
  		if ( $form ) {
  			$atts['id'] = apply_filters( 'wpml_object_id', $form->id(), Constants::POST_TYPE, true );
  		}
  
  		return $atts;
  	}
  

• For:

  	public function translate_shortcode_form_id( $atts ) {
  		$form = null;
  
  		if ( ! empty( $atts['id'] ) && is_numeric($atts['id']) ) {
  			$form = wpcf7_contact_form( (int) $atts['id'] );
  		}
  
  		if ( ! $form && ! empty( $atts['title'] ) ) {
  			$form = wpcf7_get_contact_form_by_title( trim( $atts['title'] ) );
  			unset( $atts['title'] );
  		}
  		if ($form == null){
  			$form = wpcf7_get_contact_form_by_hash( $atts['id']);
  		}
  		if ( $form ) {
  			$atts['id'] = apply_filters( 'wpml_object_id', $form->id(), Constants::POST_TYPE, true );
  		}
  
  		return $atts;
  	}
