[Bug]: "No Preview Found" when clicking on some (usually older) events in review section (0.14-beta2-rk) #11783

Describe the problem you are having

If I go to the review section, and I click on one of the events, sometimes it will go to a screen where it says "No Preview Found" in the main pane along with several "No Preview Found" along the right edge. If I go to that particular camera's history and then scroll back on the timeline to the point of the event, then I can watch it.

Steps to reproduce

Click on an event in the review section. It seems like the older the event is the more likely this is to happen. 1 hour seems to be about the threshold between working and non-working.

I don't know about beta3-rk. I'm on beta3 and I got hours of "no preview found"

I confirm I have it much less on beta 3, although I would like to understand what the root cause is.
