Target class [Middleware\AdminAuthenticated] does not exist.

since i change my routes syntax and use command "php artisan optimize:clear" i got an error related to admin role since user role works fine for me but not sure what the issue with admin since i use this tutorial to do login roles so i hope someone can clarify this issue for me in order to fix it. tutorial link: https://learn2torials.com/a/laravel8-authentication-based-on-roles full path for AdminAuthenticated.php is: projectfolder/app/Http/Middleware/AdminAuthenticated​.php
