Deprecated warnings – is it Filebird?

Hi

I have started receiving the following warnings in my WordPress admin site:

Deprecated: strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated in /homepages/43/d870750008/htdocs/clickandbuilds/WordPress/SouthportU3A/wp-includes/functions.php on line 7291

Deprecated: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in /homepages/43/d870750008/htdocs/clickandbuilds/WordPress/SouthportU3A/wp-includes/functions.php on line 2187

These lines relate to functions called wp_is_stream and wp_normalize_path respectively. Are these Filebird functions?

I am running Filebird Pro v6.3.3 on WordPress v6.5.5.

Thanks for your help
