Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires orchestra/testbench 11.* -> satisfiable by orchestra/testbench[11.x-dev]. - orchestra/testbench 11.x-dev requires laravel/framework ^13.0.0 -> found laravel/framework[dev-master, 13.0.x-dev (alias of dev-master), 13.x-dev] but it conflicts with your temporary update constraint (laravel/framework:12.*).
