- Root composer.json requires laravel/browser-kit-testing dev-develop -> satisfiable by laravel/browser-kit-testing[dev-develop].
- laravel/browser-kit-testing dev-develop requires phpunit/phpunit ^10.0.7 -> found phpunit/phpunit[10.0.7, ..., 10.5.x-dev] but it conflicts with your root composer.json require (~11.0.0).
