⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: composer.lock

Command failed: composer update drupal/core-composer-scaffold:10.6.8 drupal/core-project-message:10.6.8 drupal/core-recommended:10.6.8 --with-dependencies --ignore-platform-req=ext-* --ignore-platform-req=lib-* --no-ansi --no-interaction --no-scripts --no-autoloader --no-plugins --minimal-changes

Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires drupal/core-recommended 10.6.8 -> satisfiable by drupal/core-recommended[10.6.8].
    - drupal/core-recommended 10.6.8 requires drupal/core 10.6.8 -> found drupal/core[10.6.8] but these were not loaded, likely because it conflicts with another require.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
