Upgrading from 8.1-1.1 to 8.1-1.2

Problem/Motivation

Upgrading from 8.1-1.1 to 8.1-1.2 broke my site.
Downgrading to 8.1.1.1 restored the site.

Steps to reproduce

I am using php 8.1 and drupal version 9.4.8
Using composer to upgrade I could no longer access the site which reported "an unexpected error".
After reverting to 8.1-1.1 using composer I found the following warnings and errors at about the time of the update:
php:
Warning: Undefined array key "card_type" in Drupal\layout_builder\Plugin\Derivative\FieldBlockDeriver->getDerivativeDefinitions() (line 102 of web/core/modules/layout_builder/src/Plugin/Derivative/FieldBlockDeriver.php)
and php
Error: Call to a member function getLabel() on null in Drupal\layout_builder\Plugin\Derivative\FieldBlockDeriver->getDerivativeDefinitions() (line 113 of web/core/modules/layout_builder/src/Plugin/Derivative/FieldBlockDeriver.php)
