PHP Fatal error – AntiSpam 6.6

Hello,

I am getting the following error on one of my WP sites which is causing the site to crash occasionally.

 [03-Apr-2023 03:16:57 UTC] PHP Deprecated:  The PSR-0 Requests_... class names in the Request library are deprecated. Switch to the PSR-4 WpOrg\Requests\... class names at your earliest convenience. in /container/application/public/wp-includes/class-requests.php on line 24

I disabled the plugin and it seems working fine but when I tried to activate it again and the following fatal error occurs

The site is running WP 6.2 and PHP 7.4

Any advice would be appreciated.
