unexpected token "readonly", expecting "abstract" or "final" or "class"

Teravine

I am using Laravel v11 to make host in an application, but i am having a following error:

Parse error: syntax error, unexpected token "readonly", expecting "abstract" or "final" or "class" in /usr/home/user-project/domains/my-project.user-project.serv00.net/my-project/vendor/sebastian/version/src/Version.php on line 23.

What can it mean?

I am using PHP 8.3.12 (cli) in my PC. but my composer.json has "php": "^8.2",.

The problem is in host: PHP Version 8.1.30.
