Twice I rendered a video and the camera stops at x frame

I made a video where the camera scrolls thru a cartoon town I created to demonstrate Meshy AI has an upgrade for Meshy 5 Preview. The results are much better.

The video is simple, all it does is scroll from left to right for 7200 frames. The render appears to work and the view port appears correct as it renders. The results when rendered at about 30 - 40% of the way the camera stops scrolling and the rest of the video stays in that place.

Has anyone else ever seen this? Any known cause or solutions?

Thanks

Have you made sure your total scene frames in preferences/project settings
exceed the 7200 needed for your animation ?
