The Drupal installer will no longer display the install profile selection form.
Previously, when installing Drupal via the UI, users were presented with a step to choose between available install profiles
(e.g., Standard, Minimal, Umami). This step has been removed.
When no profile is pre-configured, the installer now defaults to the Standard install profile. Distributions, which inherently pre-select a profile, continue to work as before.
If you rely on selecting a non-default install profile during installation, this can still be done with Drush or other CLI tools, exactly as before.
The internal form class \Drupal\Core\Installer\Form\SelectProfileForm has been removed from core with no replacement. Custom installer tests that used InstallerTestBase::setUpProfile() will need to be updated, as that method and the associated form interaction no longer exist.
Alternatively you can use hook_install_tasks_alter to add the form back or use https://www.drupal.org/project/profile_selector to add it back automatically.
