Spark Billing - White Screen

Hi all, after going through the Laravel Spark installation and configuration (Stripe) setup, I get a white screen when accessing the /billing URL. I searched around here and StackOverflow for any solutions, but most I came across were either a much older version of Laravel or another product like voyager.

I have tried going through the code again but cannot find any issues, and nothing is being printed in the log.

I have used expose to expose my application and set that up in stripe.

config/spark

use App\Models\User;

    'path' => 'billing',
