How to disable device administrator that stops Settings app?

I try to disable two apps: Tasker and Applock, from device administrators, but when I tap to uncheck it, the Settings app stops. Other device admins like Cerberus can be enabled/disabled. I sent an email to Tasker developer but received this answer: > Have you disabled Tasker and restarted the device ? > > In any case, if the Settings app is stopping that's a bug in the > Settings app on your device, not in Tasker, I'm sorry to say. Tasker > has no influence on what Settings does when the button is checked or > unchecked, and you're the first person in 6 years to report a crash > in Settings from disabling the Device Admin.
