Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires phpunit/phpunit ^10.4.2 -> satisfiable by phpunit/phpunit[10.4.2, 10.4.x-dev, 10.5.x-dev].
- phpunit/phpunit[10.4.2, ..., 10.5.x-dev] require php >=8.1 -> your php version (8.0.30) does not satisfy that requirement.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
