In Drupal CMS, if you try to disable Layout Builder for a content type -- any content type -- in the UI, you'll get an exception:
TypeError: Unsupported operand types: array + null in Drupal\field_ui\Form\EntityViewDisplayEditForm->Drupal\field_ui\Form\{closure}() (line 170 of core/modules/field_ui/src/Form/EntityViewDisplayEditForm.php).
I traced this to date_augmenter_field_formatter_third_party_settings_form(), which can apparently return NULL in some situations. I am unfamiliar with the internals of this module so I'm not sure under what circumstances the NULL return can happen, but it's clearly possible.
Install Drupal CMS, and then visit /admin/structure/types/manage/page/display and disable Layout Builder for that content type.
No idea.
