¿Cómo desactivar el administrador del dispositivo que detiene la aplicación Configuración?

Intento desactivar dos aplicaciones: Tasker y Applock, de los administradores del dispositivo, pero cuando toco para desmarcarlo, la aplicación de Ajustes se detiene. Otros administradores de dispositivos como Cerberus se pueden activar/desactivar.

He enviado un correo electrónico al desarrollador de Tasker pero he recibido esta respuesta:

¿Has desactivado Tasker y reiniciado el dispositivo?

En cualquier caso, si la aplicación de Ajustes se detiene eso es un error en el aplicación de Ajustes en tu dispositivo, no en Tasker, siento decirlo. Tasker no influye en lo que hace Ajustes cuando el botón está marcado o y eres la primera persona en 6 años que informa de un fallo en la aplicación en Ajustes por desactivar el Device Admin.

logcat vía adb muestra una excepción no capturada:

¿Es posible desactivar estos administradores de dispositivos sin reiniciar el dispositivo?
