Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires phpunit/phpcov ^10.0.0 -> satisfiable by phpunit/phpcov[10.0.0, 10.0.x-dev].
- phpunit/phpcov[10.0.0, ..., 10.0.x-dev] require php >=8.2 -> your php version (8.1.29) does not satisfy that requirement.
