Reported it myself the other day - https://github.com/FMCorz/moodle-block_xp/issues/161
The issue is with PHP 8.2. Until they fix this, the only solution is to downgrade to PHP 8.1. Just to observe that while core Moodle may be compatible with a certain PHP version, it in no way means that all plugins will be.
It is, of course, just a deprecation warning. It still should work just the same.
