我正在尝试运行php工匠服务命令，但我不能.我面临这个错误
PHP Fatal error: During inheritance of ArrayAccess: Uncaught ErrorException: Return type of Illuminate\Support\Collection::offsetExists($key)
我的php版本是PHP 8.1.12（cli）.
我的composer.json文件是

"name": "laravel/laravel",
    "type": "project",
    "description": "The Laravel Framework.",
    "keywords": [
        "framework",
        "laravel"
    ],
