Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires laravel/dusk dev-develop -> satisfiable by laravel/dusk[dev-develop]. - laravel/dusk dev-develop requires php-webdriver/webdriver dev-symfony7 as 1.10.0 -> found php-webdriver/webdriver[dev-feature/driver-service-logging, dev-main, dev-legacy, v0.1, ..., v0.6.0, 1.0.0, ..., 1.15.0] but it does not match the constraint. Problem 2 - Root composer.json requires orchestra/testbench ^9.0 -> satisfiable by orchestra/testbench[9.x-dev]. - orchestra/testbench 9.x-dev requires php ^8.2 -> your php version (8.1.24) does not satisfy that requirement.
