EncryptCookies middleware 419 page expired error

I have a custom SimplePage with a form that is throwing a 419 error every time I try to submit it. I have tried also to create a filament-form component with the exact same result.

After some digging I've noticed the issue is related with the \Illuminate\Cookie\Middleware\EncryptCookies middleware and the problem goes away as soon as I remove the middleware from the panel or my custom route. Any ideas why?
Solution
Ok so looks like I've found the solution. I had to modify the AdminPanelProvider and change:

use Illuminate\Cookie\Middleware\EncryptCookies;

to:

use App\Http\Middleware\EncryptCookies;

Not sure why as the App one extends from the Illuminate class. Will leave it here in case it helps anyone.
