Your requirements could not be resolved to an installable set of packages. Problem 1 - phpspec/prophecy-phpunit is locked to version v2.2.0 and an update of this package was not requested. - phpspec/prophecy v1.19.0 requires php ^7.2 || 8.0.* || 8.1.* || 8.2.* || 8.3.* -> your php version (8.4.0; overridden via config.platform, actual: 8.4.4) does not satisfy that requirement. - phpspec/prophecy-phpunit v2.2.0 requires phpspec/prophecy ^1.18 -> satisfiable by phpspec/prophecy[v1.19.0].
