Keyboard Maestro Engine Not Responding

I have had two occurrences in the last 24 hours where the Keyboard Maestro Engine has stopped responding, both as seen in Activity Monitor.

I noticed it both times as my triggers stopped firing.

I looked at the Engine Log and see no errors.

Would appreciate guidance as to where else I can / should look to find the culprit1

Much thanks.

Use the Activity Monitor, select the Keyboard Maestro Engine and Sample the process and send it to support.

Appreciated. I will send it to you next time it happens. With a little luck it was solved by rebooting my laptop teh second time and will not reappear.

Thank you.
