I tested this on Drupal 10.1.x, standard install. I used the steps in the Issue Summary. First, I tested with the admin user and I was not able to reproduce the problem. Next, I created a user that had permission to create books, edit own books, administer content, view own unpublished content and the necessary admin book permissions. Again, I could not produce the error.
This may have been fixed as part of #26552: Allow users with access to unpublished nodes to create unpublished books β but #21 and the testing just after suggests otherwise.
Therefore, closing as outdated. If you are experiencing this problem on a supported version of Drupal reopen the issue, by setting the status to 'Active', and provide complete steps to reproduce the issue β (starting from "Install Drupal core").
Thanks!
