"Laravel Filament Login Route POST Method Not Allowed on One PC Only (Works Elsewhere)"

What I am trying to do: I'm working on a Laravel + Filament project and trying to access the admin login page (Filament default login). The project works perfectly on other PCs. What I did: Cloned the project on this machine Ran composer install, php artisan migrate, and php artisan serve The project starts correctly, and the routes are visible with php artisan route:list However, when I try to log in using /admin/login, I get a "Method Not Allowed" error on POST My issue/the error: Whenever I try to submit the login form at /admin/login, I get this error: Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException
The POST method is not supported for route admin/login. Supported methods: GET, HEAD. Code: No custom route was written for /admin/login — I am relying on Filament's default authentication setup. I also confirmed that the route exists as GET|HEAD admin/login via php artisan route:list, but no POST route is defined for it on this machine. 🧩 The weird part is that this only happens on this specific PC, while everything works perfectly on others (same project, cloned with Git).
