Unable to view attributes of an entity : message "Object reference not set to an instance of an object."
I've tried to delete an entity "ReclamationSurFacture" which is marked "Process Entity". I've had a message "This object is associated with another objects and cannot be deleted" ; the dependencies are "App\ReclamationSurFacture" et "App\DefCategory\ReclamationSurFacture".
I can edit the first dependecies but not the second ; why ?
After cancelling the delete, i can not list the attribute of my master entity "ReclamationSurFacture" ; i obtain a error and a crash of Studio.
Attached is a video presenting my problems.
Thank you for your help.
