Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires drupal/search_api_solr dev-4.x -> satisfiable by drupal/search_api_solr[dev-4.x]. - drupal/search_api_solr dev-4.x requires drupal/core ^10.1 || ^11.0 -> found drupal/core[10.1.0, ..., 10.3.0] but the package is fixed to 9.5.11 (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.
