Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires symfony/yaml ^7.0.0 -> satisfiable by symfony/yaml[v7.0.0].
    - symfony/yaml v7.0.0 requires php >=8.2 -> your php version (8.1.99; overridden via config.platform, actual: 8.1.26) does not satisfy that requirement.
  Problem 2
    - symfony/yaml v7.0.0 requires php >=8.2 -> your php version (8.1.99; overridden via config.platform, actual: 8.1.26) does not satisfy that requirement.
    - enlightn/security-checker v1.11.0 requires symfony/yaml ^3.4|^4|^5|^6|^7 -> satisfiable by symfony/yaml[v7.0.0].
    - enlightn/security-checker is locked to version v1.11.0 and an update of this package was not requested.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
