this is my first question, im creating a new post on a wp website using elementor an suddenly this error is coming up to this new post that im building:

Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /srv/vhost//home/html/wp-includes/formatting.php on line 578

Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, bool given in /srv/vhost//home/html/wp-includes/formatting.php:3495 Stack trace: #0 /srv/vhost//home/html/wp-includes/class-wp-hook.php(324)… and continues with the stack trace

Thank you.

i already tried to change formting.php to check that the parameter is not null or empty but its creating a lot new errors, at least i want to know if there is any new component that is creating the error or how can i fix it
