Since EntityOwnerTrait can be used as a default implementation of EntityOwnerInterface → the owner can't be NULL anymore for media entities.
Therefore if you cancel a user you can't edit a media entity that was own by this user. The following error is thrown:
Drupal\Core\Entity\EntityStorageException: SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column "uid" violates not-null constraint DETAIL: Failing row contains (188, 241, image, nl, 1, building-buildings-busy-297743_0.jpg, 442, car, null, 1000, 667, null, 1558535344, 1563353147, 1, 1).: INSERT INTO drupal_webshop_nl.media_field_data (mid, vid, bundle, langcode, status, name, thumbnail__target_id, thumbnail__alt, thumbnail__title, thumbnail__width, thumbnail__height, uid, created, changed, default_langcode, revision_translation_affected) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8, :db_insert_placeholder_9, :db_insert_placeholder_10, :db_insert_placeholder_11, :db_insert_placeholder_12, :db_insert_placeholder_13, :db_insert_placeholder_14, :db_insert_placeholder_15); Array ( ) in Drupal\Core\Entity\Sql\SqlContentEntityStorage->save() (line 847 of /var/www/html/src/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).
(Captain Obvious Note: When updating the media entity if you add an owner no errors are thrown.)
I open this issue for people who need a temporary solution.

✨
Provide a Entity Handler for user cancelation
Needs work
try to find a generic solution and could take a while.
The first proposed solution is a no-brainer: copy/paste what is done for node.
Find a quick win better than copy/paste while waiting for ✨ Provide a Entity Handler for user cancelation Needs work .

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Because #3043725: Provide a Entity Handler for user cancelation ✨ Provide a Entity Handler for user cancelation Needs work is not ready yet, I rerolled this quick fix against drupal 11.x-dev.
And another patch specifically for Drupal 11.1.7. Apparently the latest D11 dev version already differs from Drupal 11.1.7.
So when you are higher than Drupal 11.1.7, you might need the patch posted in #39.
