I'm working with Laravel version 8.53.1 and I have tried these commands to install Bootstrap authentication with Laravel:
composer require laravel/ui
php artisan ui bootstrap 
php artisan ui bootstrap --auth
npm install  && npm run dev 
But now the problem is the Login & Register blades do not read Bootstrap, and the forms look like this:
I have even repeated running the command several times, but still, the problem exists! What's going wrong here?

So how can I solve this issue? I have also tried removing caches by running php artisan cache:clear and php artisan view:clear, but it didn't solve the issue.
