After The above curly bracket is where the problem appears you had second else statement, the first else without if statement is near this is where initial load begins you missed the logic.
I cleaned up your code a bit and corrected the error, in the future pay attention to not repeat your code. In each statement you had opening div with the same class name, I moved them before the conditions.
<?php
while ( have_posts() ) : the_post();
$initialCardLoad = 5;
$loopLazyLoad = 0;
$galleryType = get_field( 'gallery_type' ); ?>
<section class="grid-content">
<div class="gridGallery <?php the_title_attribute(); ?>">
<?php
// check if the repeater field has rows of data
if ( have_rows( 'card' ) ) {
// loop through the rows of data
while ( have_rows( 'card' ) ) :
the_row();
$loopLazyLoad ++; // iterate on loop each time you loop through
// display a sub field value inside a card
//VARIABLES//
$title = get_sub_field( 'card_title' );
$childImage = get_sub_field( 'card_picture' );
$file = get_sub_field( 'card_video' );
$video = $file['url'];
$videoTitle = get_sub_field( 'card_video_title' );
