Exception not getting Caught in childHtml

I have a try catch block where inside of try I navigate to different set of childHtml based on a if-else in the parent .phtml file and if there is any error, I need to catch them. Problem is, the exceptions are not getting caught by the try catch block. Any issues inside the childHtml is getting added to the exception.log. Following is the try-catch block.

            try {
            if ($var1)
                echo $block->getChildHtml('template_1');
            elseif($var2) {
                echo $block->getChildHtml('template_2');
            } elseif ($var3) {
                echo $block->getChildHtml('template_3');
            } else {
                echo $block->getChildHtml('template_4');
            }
            
            } catch (Exception $e) {
                //Some stuff.
            }
            ?>

For instance, I have an error in template_1, I expect it to be catched inside the above catch block. It is happening if it is in a developer mode. But not in a prod mode. Not sure if that is the problem here. Can anyone guide me out of this please. Thanks in advance.
