The job was canceled because "_7_1_7" failed.

Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpstan/phpstan ^2.1 -> satisfiable by phpstan/phpstan[2.1.0, 2.1.1]. - phpstan/phpstan[2.1.0, ..., 2.1.1] require php ^7.4|^8.0 -> your php version (7.3.33) does not satisfy that requirement.
