Apologies if this is a bug that has already been fixed. I havent updated in a couple of months (generally I dont update unliess I'm at the observatory to verify all ok)

So I was using the scheduler and normally its fine, works perfect. But I noticed tonight, it got caught in a loop. Easiest to explain by video below.

Any idea what could be going on?
I've tried to add the video linline in this post but I'm not sure how.... Please click the attachment to see it

This is an issue with the altitude constraint. You have a minimum altitude set to 40 degrees for your target, and the Scheduler has a bug which re-schedules the constrained job even if it's altitude is too low. Therefore the job keeps starting execution, and aborting on runtime check of the constraint.
The issue happens when the job is interrupted by the altitude constraint: from there, it loops indefinitely. D16429 fixes that erroneous behavior, but in the meantime, you should avoid terminating a job from its altitude.

Thanks Eric for the explanation.
