ظهور الخطأ conflict with contracts أثناء تحميل Sanctum في لارافل

لدي نسخة سابقة من مشروع لارافل وأحاول إضافة مكتبة sanctum إليه. ولكن عندما أقوم تحميل sanctum من خلال composer أحصل على الخطأ التالي:

Your requirements could not be resolved to an installable set of packages. Problem 1 - laravel/sanctum[v2.9.0, ..., 2.x-dev] require illuminate/contracts ^6.9|^7.0|^8.0 -> found illuminate/contracts[v6.10.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require. - Root composer.json requires laravel/sanctum ^2.9 -> satisfiable by laravel/sanctum[v2.9.0, ..., 2.x-dev].

حاولت حل رسالة الخطأ هذه من خلال تحميل contracts في لارافل من التوثيق الرسمي:

composer require illuminate/contracts

ولكن ظهرت أخطاء جديدة:

Your requirements could not be resolved to an installable set of packages.

Problem 1 - Root composer.json requires illuminate/contracts ^8.36, found illuminate/contracts[v8.36.0, v8.36.1, v8.36.2, 8.x-dev] but these were not loaded, likely because it conflicts with another require.
