Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires seec/behat-magento2-extension @dev -> satisfiable by seec/behat-magento2-extension[dev-master, dev-5c60cb10a2a22aedc92c9ebb21ed529bf94daf61]. - seec/behat-magento2-extension[dev-master, dev-5c60cb10a2a22aedc92c9ebb21ed529bf94daf61] require seec/behat-test-runner ^8 -> found seec/behat-test-runner[8.2, ..., 8.2.4] but the package is fixed to 9999999-dev (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. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
