Error when posting in my phpBB board with php 8.2.9

So i want to switch my php version from 7.3 (default) to the 8.2 in the admin panel but when I do I'm getting an error on posting page on my board.

Code:

---

[phpBB Debug] PHP Warning: in file [ROOT]/vendor/symfony/http-foundation/File/MimeType/FileBinaryMimeTypeGuesser.php on line 60: Undefined variable $exitStatus

---

You can see the error in action here https://mannix.altervista.org/postin...mode=post&f=11

Hello!

PHP 8.2.9 has more restrictitives rules, probably there is some use of $exitStatus variable before of initialization.

Did you check this table? What's your current drupal version?

Bye!
