Replicated in the above personal demo.
I have created a Divisions entity with status field id 214 and added this to the User entity as an entity ajax field- id 215 set to the Divisions entity. When I add the condition
to the field the error appears in the console and there are no items in the dropdown where there should be one.field_214 != 69
bug is with file includes\classes\fieldstypes\fieldtype_entity_ajax.php foreach loop on line 585 which can't handle field 6 access groups being an array.Failed to load resource: the server responded with a status of 500 (Internal Server Error)
In my own dev I can see the PHP error as
Uncaught Error: [] operator not supported for strings in ...\includes\classes\fieldstypes\fieldtype_entity_ajax.php:595
