Workaround
For the time being, what you need to do is change the assignee fields to not be "REQUIRED" within the database.
Before making any changes to the DB, please shut Jira down, and make a backup of your database.
Run the below query to change the fields:
UPDATE "AO_54307E_VIEWPORTFIELD" SET "REQUIRED" = 'false' WHERE ("FIELD_ID" = 'assignee' OR "LABEL" = 'Assignee') AND "REQUIRED" = 'true';Start Jira up again and try removing the fields from within the Jira UI.
