Sort posts by meta key query

Hi,
I’m looking to sort multiple posts into lists after the query.
I have to query the posts using a taxonomy term that is a field and then have all these posts sorted in different year by an other field.

I want to have lists with the year as title like this:
2021:
post
post
post

2020:
post
post
post

etc.

Here’s my code right now:

<?php 	$topics = get_sub_field('sous-categories-en-avant');
							
						if ($topics) {
						  if (!is_array($topics)) {
						    $topics = array($topics->slug);
						  }
						  $args = array(
						    'post_type' => 'production',
						    'posts_per_page' => -1,
						    'order' => 'DESC',
						    'meta_key'			=> '_production_year',
							'orderby'			=> 'meta_value',
						    'tax_query' => array(
						      array(
						        'taxonomy' => 'production-category',
						        'field'    => 'slug',
						        'terms' => $topics,
						      ),
						    ),
						   
						  );
						  $production_query = new WP_Query($args);
					
						  if ($production_query->have_posts()) $count = 0; {?>
						 		<div class="grid" data-packery='{ "itemSelector": ".grid-item", "gutter": 10 }'>
					

						 
									 <?php while($production_query->have_posts()) {
							      $production_query->the_post();  ?>		

								  	<?php $year = get_field('_production_year');?>											  	
									

									<?php if ($count > 0 && (($count % 2) == 0)) {?>
										<div class="grid-item">
									<?php  } else{?>		    
										<div class="grid-item grid-item--width2">
									<?php }?>
											<a href="<?php the_permalink();?>">
										
												<div class="productions-archives-thumb">
													<?php the_post_thumbnail( 'medium','');?>
												</div>
												<div class="productions-archives-text">
												    <?php the_title();?>
												    <?php the_field('_production_year');?>
												</div>
										    
										    </a>
										</div>
										

							     
							  <?php   $count++; }?>
							  
						  </div><!-- grid-->
						<?php   }
						  wp_reset_postdata();
						}?>

I hope that someone can help me with this, thanks by advance, best
