XF 2.3 HTTP ERROR 500 after upgarde 2.3.10

[Radhi]

Hello, after upgrading the forum to version 2.3.10, I can't log in or access the control panel.

It says "HTTP ERROR 500" and my PHP version is 8.3.

What's the solution? Thank you.

disable the addons using config.php

$config['enableListeners'] = false;

then debug which addon is causing it. Most probably an addon that is not compatible with XF 2.3 is causing it.
