Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires cakephp/utility ^5.0.11 -> satisfiable by cakephp/utility[5.0.11].
- cakephp/utility 5.0.11 requires php >=8.1 -> your php version (7.4.7; overridden via config.platform, actual: 8.3.11) 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.
