Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/symfony 6.4 (exact version match: 6.4, 6.4.0 or 6.4.0.0), found symfony/symfony[v6.4.0] but these were not loaded, because they are affected by security advisories. To ignore the advisories, add ("PKSA-nqwp-2kdm-491t", "PKSA-yvfh-tnnw-3w9h", "PKSA-jdmc-h4p3-hds2", "PKSA-19z7-hn1j-mtcg", "PKSA-vxd1-4ssb-3qdw", "PKSA-rb2q-qy38-2dj7", "PKSA-2dqt-6z5j-rcvr", "PKSA-nmpz-hw89-qbtt", "PKSA-365x-2zjk-pt47", "PKSA-b35n-565h-rs4q", "PKSA-wws7-mr54-jsny") to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config.
