Errors in plugin

Hey guys, I am using your plugin for years, but now I see some issues here on a WPhive test with PHP errors, PHP 8.1 compatibility issues: https://wphive.com/plugins/all-in-one-wp-security-and-firewall/

I found this because I have CPU spikes so I am checking all my plugins. Hopefully you can fix this.
