unserialize() error on D10

Problem/Motivation

Whenever enabling the module on Drupal 10 I get unserialize(NULL) error.
It happens in web/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php, Line 604:

$values[$id][$field_name][$langcode][$property_name] = (!empty($column_attributes['serialize'])) ? unserialize($row[$column_name]) : $row[$column_name];

The full message is this:

Deprecated function: unserialize(): Passing null to parameter #1 ($data) of type string is deprecated in Drupal\Core\Entity\Sql\SqlContentEntityStorage->loadFromSharedTables() (line 604 of core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php).

Indeed, the table menu_link_content_data has column translated_link_url__options, and the values are all NULL.

Running this

update menu_link_content_data set translated_link_url__options = 'N;';

will fix the issue.

Steps to reproduce

My scenario was following:

1. Installed D9
2. Installed multilingual_menu_urls
3. Created a multilingual external url
4. Upgraded to D10
5. Cannot do even drush cr because of the unserialize(NULL) errors.
6. Fixed by the above update query

It can be repeated:

1. drush pm-uninstall multilingual_menu_urls
2. drush en multilingual_menu_urls
3. drush cr ... and the error appears again.

Proposed resolution

Install hook that takes care of converting that serialized field from NULL to N;.
