BaseFieldOverride fails to take into account ContentEntityInterface::bundleFieldDefinitions() when invoking onFieldDefinitionUpdate()

Patch in #37 🐛 BaseFieldOverride fails to take into account ContentEntityInterface::bundleFieldDefinitions() when invoking onFieldDefinitionUpdate() Needs work worked for me.
I was getting the error below when saving the configuration in the Content Traslation page (/admin/config/regional/content-language). It generated override files for fields of one of the entities provided by the Recurring Events → module.
Then, after exporting the configuration and trying to import it in another environment, I got this:

TypeError: Argument 2 passed to Drupal\Core\Entity\ContentEntityStorageBase::onFieldDefinitionUpdate() must implement interface Drupal\Core\Field\FieldDefinitionInterface, null given, called in /app/web/core/lib/Drupal/Core/Field/Entity/Base  
  FieldOverride.php

Thanks for looking into this and providing the patch.

The patch at #37 has helped me on D9.5

I'd been trying to uninstall modules and getting lots WSOD/errors:

TypeError: Drupal\Core\Entity\ContentEntityStorageBase::onFieldDefinitionUpdate(): Argument #1 ($field_definition) must be of type Drupal\Core\Field\FieldDefinitionInterface, null given, called in web/core/lib/Drupal/Core/Field/Entity/BaseFieldOverride.php on line 222 in Drupal\Core\Entity\ContentEntityStorageBase->onFieldDefinitionUpdate() (line 546 of web/core/lib/Drupal/Core/Entity/ContentEntityStorageBase.php)

#37 also worked for me on D9.5.8. Was getting the same error as #68.

Just stating that in my 9.5.10 install #37 didn't work but #39 did

Reroll of #39 for Drupal 10.1.x

Patch in #71 worked for me. I'm on Drupal 10.1.6, PHP 8.1.
