When adding (trying to add) a field to a content type, on page /admin/structure/types/manage/MY_TYPE/fields/add-field, the following error occurs:
The website encountered an unexpected error. Try again later.

This is because WorkflowItem is defined incorrectly.
/**
* Plugin implementation of the 'workflow' field type.
*
* @FieldType(
* id = "workflow",
* category = @Translation("Workflow"), // <== This must be untranslated.
* ...
* )
*/
the marked line must be changed to
* category = ("Workflow",
Not sure why this happens.
I never experienced a problem, until I de-activated the Workflow module on D11.2, then enabled it again and added back a field.
