Animated Lower Third stops Working V1.6 on OBS 26.1.1 Windows 10

All of a sudden my deployment stopped working the panel shows blue but nothing shows in preview or program screen. This is with rest of the layer disabled. Is their a log that I can read and report or alternatively any dependencies that am missing.

I've had exactly this happen with a system i only setup in the last month. Did you ever find a cause and resolve this?

My issue was that I'd ticked the box "Local File" when adding the browser source. Removing this checkbox returned the functionality.
Hope this helps others searching this behaviour.
