Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires composer/composer 2.0 (exact version match: 2.0, 2.0.0 or 2.0.0.0), found composer/composer[2.0.0] but these were not loaded, because they are affected by security advisories ("PKSA-1gck-s111-yq7g", "PKSA-s25b-vbmp-jvhh", "PKSA-b8f7-zn44-r4gz", "PKSA-jn72-4kr8-gj3h", "PKSA-m1ph-vmbx-2xd3", "PKSA-6zmq-d6mk-r5wm", "PKSA-93hy-9dc1-gbwt", "PKSA-9p8h-97x3-qxpm"). Go to https://packagist.org/security-advisories/ to find advisory details. To ignore the advisories, add them to the audit "ignore" config. To turn the feature off entirely, you can set "block-insecure" to false in your "audit" config.
