Fixed the UI booting problem. But like cutehunk04 said, pressing the Lock button in the UI doesnt seem to do anything. Applications are still unlocked. And for your reference, I even restarted the daemon through command line even though UI reported the daemon is running.

and applock-d in the termnal gives this output:

~ $ applock -d
