This is the error I got when I turned on the debugger in wp-config.php:

I tried removing autop so many ways in the past but I had an issue where it caused a fatal error anytime I tried to use the Contact Form 7 plugin. I think there needs to be a fixed in the next release.
//remove autop from everywhere
remove_filter('widget_text_content', 'wpautop');
remove_filter('the_excerpt', 'wpautop');
remove_filter('the_content', 'wpautop');
remove_filter('widget_text_content', 'wpautop');
remove_filter('the_content', 'wptexturize');
add_filter('widget_text_content', 'leadstart_removing_autop', 999);
add_filter('widget_custom_html_content', 'leadstart_removing_autop', 999);
function removing_autop($content)
{
$content = str_replace(['<p>', '</p>'], ['', ''], $content);
return $content;
}I am using PHP version 8.1.
