AssertionError: "Media" must be defined in MODULE_NAME.field_type_categories.yml in assert()

Problem/Motivation

I upgraded my project and now when I try to add a field to a content type that has a ics_field, I get the following WSOD:

The website encountered an unexpected error. Try again later.

AssertionError: "Media" must be defined in MODULE_NAME.field_type_categories.yml in assert() (line 183 of core/lib/Drupal/Core/Field/FieldTypePluginManager.php).

Steps to reproduce

I think having an existing project with content type that has an ics_field and then upgrading Drupal core to 11.1.4
Probably even on earlier versions. I think this change record → is very relevant.

Proposed resolution

Edit ics_field/src/Plugin/Field/FieldType/CalendarDownloadType.php
Change:
* category = @Translation("Media"),
Into something like:
* category = "reference",
