Use a ternary operator.
Before Codeigniter existing code:
$output = str_replace(array('{elapsed_time}', '{memory_usage}'), array($elapsed, $memory), $output);
Hopefully, it's will work fine.
After Use Ternary Operator:
$output = $output ? str_replace(array('{elapsed_time}', '{memory_usage}'), array($elapsed, $memory), $output): "";

This error message can show up if you have not loaded any views. Codeigniter's internal output buffer is never initialized thus being null. The output buffer is the third parameter to str_replace(). There might be other ways to trigger this error message.
You probably want to load a valid view, at some point.
PHP 7 and lower just would ignore the missing parameter, while PHP 8+ displays the warning. It may also vary with your environment / debug settings.
