BBT not activating after powering on iMac


I have been using BTT for a few years on an iMac and my experience has been excellent.
Normal behavior includes BTT launching on its own each time I turn on my iMac; however, as of last week, each day I turn on the iMac, BTT is not launching and I have to do so manually.

Been trying to find the answer through my settings, etc but to no avail.
Anyone have a solution.

In advance, thank you.

Really disappointed no one has provided feedback regarding my question after almost three weeks.
I also sent an email to the creator of the application.
