I get the same issue when trying to update the settings in the customiser.

An example of the full response from admin-ajax.php is this:

{"success":false,"data":{"message":"","code":"changeset_post_save_failure","setting_validities":{"blogdescription":true},"changeset_post_save_failure":"db_insert_error"}}

The database user has full permissions and has no problem updating things like posts or other areas of the site.

Anyone have any ideas?

Aha! It works when the [tagcloud] shortcode is used in the post, so I just need to hide the tagcloud itself and the permalinks will work that way.

I just found my own answer, hopefully it’ll help anyone else.
