How to kill a notebook process

[ChrisCowin]

I've tried everything I can think of to kill a running notebook that is stuck in a loop and nothing works. The Interrupt Kernel button is always grayed out, tried restarting the kernel through the command prompt (P Key) but this doesnt seem to do anything either. The only way I've figured out how to stop the process is to kill the entire application in task manager.

In the notebook tab in the top banner you can click "interrupt kernel". I've done this a few times with success, unless ArcPro isn't responding at all, then I find this button can be greyed out.
