views_embed_view not loading template in PHP 8.0

I'm using this script in rules to add a view to an email. It is no longer working now that I'm on php 8.0

@museumboy: I suggest reviewing your custom code, there might be something that needs to be fixed in it.

@JOINSO: please test the latest dev release, see if it resolves the problem.

@DamienMcKenna:
Thanks for the tip.
Few months ago, we released the new version of our site that is working with PHP 8.0 and D7.
Our solution was change this:
echo views_embed_view('usercomments', 'block');
To this:

  $view = views_get_view('usercomments');
  $view->set_display('block');	  
  $view->pre_execute();
  $view->execute();
  if(count($view->result)>0)
  {
		?>
            <div class="view-content">
            <br/><br/><strong><?php echo t('My Reviews');?></strong><br/><br/>
            <table>
              <tr>
                <td>
                  <?php echo t('Review Id');?>
                </td>
                <td>
                  <?php echo t('Edition Date');?>
                </td>
                <td>
                  
                  <?php echo t('Review Preview');?>
                </td>
                <td>
                  <?php echo t('Published on');?>
                </td>
                <td>
                  <?php echo t('Type');?>
                </td>
                <td>
                  <?php echo t('Subscription');?>
                </td>
                <td>                  
                  <?php echo t('Actions');?>
                </td>
              </tr>   
            <?php
            foreach($view->result as $key => $row)
            {
              $nodeComment=node_load($row->comment_nid);
              $commentNotify=array();
              $commentNotify[$row->cid]=(object)[];
              comment_notify_comment_load($commentNotify);
              		    ?>
          		      <tr>
          		        <td>
              	        <?php echo $row->cid;?>
              	      </td>
              	      <td>
              	        <?php echo date("Y-m-d h:i:s",$row->comment_changed);?>
              	      </td>
              	      <td>
              	        <?php echo f4r_tools_truncate_html($row->_field_data['cid']['entity']->comment_body['und'][0]['value'],20);?>
              	        
              	      </td>
              	      <td>
              	        <?php 
              	        echo $nodeComment->title;
              	        ?>
              	      </td>
              	      <td>
              	        <?php echo $nodeComment->type;?>
              	      </td>
              	      <td>
              	        <?php 
              	        if($commentNotify[$row->cid]->notify)
              	        {
              	          echo t('Subscribed');
              	        }
              	        else
              	        {
              	          echo t('Unsubscribed');              	          
              	        }
              	        ?>
              	      </td>
              	      <td>
              	        <a class='linkMyContent' href="/comment/<?php echo $row->cid;?>" target="_new"><?php echo t('View');?></a> | 
              	        <a class='linkMyContent' href="/comment/<?php echo $row->cid;?>/edit" target="_new"><?php echo t('Edit');?></a>
              	      </td>		        
          		      </tr>
              
              <?php
            }	  
            ?>
          	  </table>  
          	  <?php    
		echo theme('pager'); 
  }

At the moment I am not going to make more test because I am focused in migrating D7 to D10.
Hope this workaround can help other ones to fix the issue.

I noticed that there's no test coverage for views_embed_view(), so let's add some.

A starting point for test coverage on views_embed_view().

I've set the tests to run against both PHP 7.4 and 8.0, so we'll see if a basic view works as expected.

The test coverage shows the same output working for both PHP 7.4 and 8.0. I suggest you both look into the specific views that are failing for you and see if any of them include custom PHP code, that could be the culprit.
