Solution 1:[1]

Since Laravel version 8, controller route definitions must be defined using standard PHP callable syntax:

Basic Controllers

use App\Http\Controllers\SiteController;

Route::get('/', [SiteController::class, 'home']);
Route::get('/about', [SiteController::class, 'about']);
Route::get('/contact', [SiteController::class, 'contact']);

You may use the route:clear command to clear the route cache:

php artisan route:clear

Solution 2:[2]

Please run the command, I think some cache has occured.

php artisan config:cache

php artisan optimize:clear
