Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires orchestra/testbench 7.* -> satisfiable by orchestra/testbench[v7.0.0, ..., v7.50.0]. - orchestra/testbench[v7.0.0, ..., v7.50.0] require phpunit/phpunit ^9.5.10 -> found phpunit/phpunit[9.5.10, ..., 9.6.22] but it conflicts with your root composer.json require (^10.5).
