Your requirements could not be resolved to an installable set of packages. Problem 1 - rector/rector[0.19.2, ..., 0.19.8] require phpstan/phpstan ^1.10.56 -> found phpstan/phpstan[1.10.56, 1.10.57, 1.10.58, 1.10.59] but the package is fixed to 1.10.32 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. - craftcms/rector dev-main requires rector/rector ^0.19.2 -> satisfiable by rector/rector[0.19.2, ..., 0.19.8]. - Root composer.json requires craftcms/rector dev-main -> satisfiable by craftcms/rector[dev-main]. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
