I have opened a thread for probably the same issue.
But we’re still trying to identify the conditions and context it appears in.
So to check if it’s the very same symptom, please log:set debug org.openhab.core.automation
Reduce binding logging to a minimum to not fog the relevant messges too much.
Now post the relevant lines from openhab.log here (or better on the linked thread).
I mean those lines about dependencies and rule engine not starting plus anything before that might be related to the problem.
