The "dealerdirect/phpcodesniffer-composer-installer" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.

  Problem 1
    - dealerdirect/phpcodesniffer-composer-installer v0.6.2 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.
    - doctrine/coding-standard 8.0.0 requires dealerdirect/phpcodesniffer-composer-installer ^0.6.2 -> satisfiable by dealerdirect/phpcodesniffer-composer-installer[v0.6.2].
    - Root composer.json requires doctrine/coding-standard ^8.0 -> satisfiable by doctrine/coding-standard[8.0.0].

You are using a snapshot build of Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report an issue to them to ask them to support Composer 2. To work around this you can run Composer with --ignore-platform-req=composer-plugin-api, but this may result in broken plugins and bigger problems down the line.
