5.3.10 throwing Call to undefined function error

On updating to 5.3.10 our error logs immediately started rapidly filling with the following error.

[26-Mar-2025 17:23:07 UTC] AIOS firewall error: Call to undefined function AIOWPS\Firewall\wp_parse_url()

Rolling back to 5.3.8 stopped the errors. I didn’t leave the update installed for long enough to observe any actual errors/issues occurring on the site.
