Your lock file does not contain a compatible set of packages. Please run composer update. Problem 1 - vimeo/psalm is locked to version 6.4.0 and an update of this package was not requested. - vimeo/psalm 6.4.0 requires php ~8.1.17 || ~8.2.4 || ~8.3.0 || ~8.4.0 -> your php version (8.1; overridden via config.platform, actual: 8.1.33) does not satisfy that requirement.
