I have GO Security on my Galaxy S6 and can't close it

AC Question

I like the app but currently it has been on "cooling down CPU 2/6 for the last four hours. I tried to turn off my phone but I can't by pushing the power button and can't cancel it either - I cannot get to any menus or tools while this is running. Currently trying to let my battery drain so the phone will turn off and hopefully stop the app. I know they had an upgrade on 3/18 so not sure if that has anything to do with it or not but my phone is a brick right now. :(
